Abstract:
After almost 40 years of research on EEG computer analysis, present clinical applications of this method remain limited. At the present time, EEG mapping is suited primarily for research. Despite the pitfalls of an uncritical application of EEG mapping, progress in clinical research made possible by EEG mapping techniques has been considerable. Some problems of data acquisition, display and statistical analysis are discussed in this paper. For headache research examination of the activated EEG, especially with photic stimulation, has greater diagnostic importance than mapping under resting conditions.

Abstract:
To understand how the brain functions, we must investigate the transient interactions that underpin communication between cortical regions. EEG possesses the optimal temporal resolution to capture functional connectivity, but it lacks the spatial resolution to identify the cortical locations responsible. To circumvent this problem electrophysiological connectivity should be investigated at the source level. There are many quantifiers of connectivity applied to EEG data, but some are not sensitive to the direct, or indirect, influence of one region over another, and others require the specification of a priori models so are unsuitable for exploratory analyses. Transfer Entropy (TE) can be used to infer the direction of linear and non-linear information exchange between signals over a range of time-delays within EEG data. This thesis explores the creation of a new method of mapping dynamic brain connectivity using a trial-based TE analysis of EEG source data, and the application of this technique to the investigation of semantic and number processing within the brain. The first paper (Chapter 2) documents the analyses of a semantic category and number magnitude judgement task using traditional ERP techniques. As predicted, the well-known semantic N400 component was found, and localised to left ATL and inferior frontal cortex. An N365 component related to number magnitude judgement was localised to right superior parietal regions including the IPS. These results offer support for the hub-and-spoke model of semantics, and the triple parietal model of number processing. The second paper (Chapter 3) documents an analysis of the same data with the new trial-based TE analysis. Word and number data were analysed at 0-200ms, 200-400ms, and 400-600ms following stimulus presentation. In the earliest window, information exchange was occurring predominately between occipital sources, but by the latest window it had become spread out across the brain. Task-dependent differences of regional information exchange revealed that temporal sources were sending more information to occipital sources following words at 0-200ms. Furthermore, the direction and timing of information movement within a front-temporal-parietal network was identified during 0-400ms of the number magnitude judgment. The final paper (Chapter 4), documents an attempt to track the influence of TMS through the brain using the TE analysis. TMS was applied to bilateral ATL and IPS because they are both important hubs in the brain networks that support semantic and number processing respectively. Left ATL TMS influenced sources located primarily in wide-spread left temporal lobe, and inferior frontal and inferior occipital cortices. The anatomical connectivity profile of the temporal lobe suggests that these are all plausible locations, and they exhibited excellent spatial similarities to the results of neuroimaging experiments that probed semantic knowledge. The analysis of right ATL TMS obtained a mirror image of the left. Left parietal stimulation resulted in a bilateral parietal, superior occipital, and superior prefrontal influence, which extended slightly further in the ipsilateral hemisphere to stimulation site. A result made possible by the short association and callosal fibres that connect these areas. Again, the results at the contralateral site were a virtual mirror image. The thesis concludes with a review of the experimental findings, and a discussion of methodological issues still to be resolved, ideas for extensions to the method, and the broader implications of the method on connectivity research.

Abstract:
Current language mapping protocols for neurosurgical planning are invasive, expensive, and not suitable for all surgical candidates. We investigated the potential of dense array EEG to determine hemispheric dominance for language and localize current sources of semantic and lower level language functions in the brain using a semantic decision task, a phonological decision task, and an acoustic decision task. Source estimates of N400-window ERPs (N365, N480) and the Late Positive Complex (LPC) localized strongly to medial temporal regions. Overall source estimates revealed a slight left lateralized network, with more posterior engagement for the semantic condition and more anterior engagement for the phonological condition. Source localization of the resulting t-test wave from the semantic - phonological highlighted a stronger left lateralized pattern of activation encompassing more of the semantic network. As a first pass these results are promising, but need to be investigated on individual subject ERPs.

Abstract:
Functional dysconnectivity has been proposed as the cause of schizophrenia. This thesis proposes a model with increased neural synchrony in the gamma band (30-100 Hz) as the underlying physiological mechanism responsible for this dysconnectivity. The model is tested by examining cognition, electroencephalogram (EEG) gamma synchrony, and functional magnetic imagining (fMRI) functional connectivity, and their interrelationships, in participants with first onset schizophrenia (FOS) and matched controls. All responses were elicited by a standard paradigm of attention – the Continuous Performance Test (CPT). This is the first direct comparison across these units of analysis in schizophrenia using the same paradigm. FOS showed impaired CPT cognitive performance (best measured by accuracy; n=75). The modulation of gamma synchrony to task-evoked changes was reduced in FOS (n=59), in the context of generally higher intrinsic synchrony, particularly in frontal regions. FOS (n=22) showed abnormal fMRI functional connectivity, measured from a DLPFC seed, with decreased connectivity to the inferior parietal cortex and increased connectivity to the dorsal anterior cingulate cortex. These findings support a model of schizophrenia as a disorder of excessive intrinsic brain connectivity with a failure to recruit appropriate task-induced activity. However, when interrelationships were examined pair-wise (EEG-cognition, fMRI-cognition, EEG-fMRI), they were more complex than hypothesized and did not integrate well into the model. A case-series (n=15 FOS; n=13 controls) examining interactions among all three measures provided further evidence of this complexity. The results highlight the importance of integrating across different units of analysis using the same task in the same participants, as it was the relationships among measures that challenged the model. The findings undermine schizophrenia simply as a disorder of abnormal functional connectivity caused by aberrant gamma synchrony.

Abstract:
The research investigates the dynamic relations between sound, space and the audience perception as related to an artist’s intention. What is the relation between sound and space in the sonic arts, and to what kind of merger does it lead? What relationship exists between the intention of the composer and the perception of the audience regarding architectural and environmental spaces? Is there a common thread of perception of architectural and environmental spaces among participants? Is embodiment a key for the perception of the dynamic relations of sound and space? The framework for the investigation is based on a map of three defined spaces (Real, Virtual, and Hyperbiological) included in a portfolio of six works (three electroacoustic compositions, two sound installations, and one performance), which lead to the analysis of the perception of space, namely, the perception of architectural and environmental spaces as required by the portfolio. The original knowledge resides in the exploration of a potential common representation (space and sound perception being, of course, a personal representation) of internal perceptual spaces and mental imageries generated by the works. The act of listening plays a major role in the development of the portfolio presented and includes Pauline Oliveros’ concept of deep listening (Oliveros 2005). Sound and space are intimately related in the portfolio. One particular element emerging from this relationship is the plastic quality of sound, meaning that sound is considered and observed as a material that is shaped by space. From this perspective the research investigates the ‘sculptural’ and morphological quality of the relationship between sound and space. The results include the specific language and signature of the artworks that delineate the intersection of music and fine arts. The portfolio pays a large tribute to several iconic artists present in the outposts of sound blurred by space. Composers and artists are therefore presented in the theoretical section in order to highlight how their pioneering works have influenced and informed the present research portfolio. The analysis of the perception of the artworks relates to a methodology based on an empirical survey inspired by phenomenology.

Abstract:
O mapeamento das respostas BOLD (Blood Oxygenation Level Dependent) constitui etapa importante nos experimentos de imagem funcional por ressonância magnética (Functional Magnetic Resonance Imaging fMRI) e de EEG-fMRI simultâneo. Em sua grande maioria, a análise de dados de fMRI e de EEG-fMRI está baseada no modelo linear geral (General Linear Model GLM), que procura localizar as respostas BOLD por meio de modelos definidos a priori. Porém, em muitos casos, como em pacientes, variações na forma e/ou atraso podem reduzir a confiabilidade dos resultados. Desse modo, o primeiro objetivo deste trabalho foi explorar métodos clássicos e propor novos métodos para análise de dados de fMRI e de EEG-fMRI simultâneo. Neste trabalho, um método modificado baseado na distância de Kullback-Leibler generalizada (dKLg) foi desenvolvido. Diferentemente do GLM, essa abordagem não requer um modelo para a resposta. Dados simulados foram utilizados para otimizá-lo e compará-lo ao GLM sob diferentes condições de resposta como a relação sinal ruído e a latência. Em seguida, o dKLg foi testado em dados reais, adquiridos em 14 voluntários assintomáticos, submetidos a tarefas motoras e auditivas padrões. Os resultados mostram a equivalência entre o dKLg e o GLM. Em seguida, essa estratégia foi testada em 02 pacientes com com estenose carotídea unilateral. Neste caso, o dKLg foi capaz de detectar regiões significativas ipsilaterais à estenose, não detectadas pelo GLM, em virtude do atraso do sinal BOLD. Em seguida, esses métodos foram aplicados sobre exames de EEG-fMRI realizados em 45 pacientes com epilepsia. Para esse conjunto de dados, mais uma abordagem foi elaborada, que utiliza a Análise de Componentes Independentes (Independent Component Analysis ICA). Denominado ICA-GLM, ele permite extrair de modo semi-automático a amplitude, duração e topografia das descargas epileptiformes interictais (Interictal Epileptiform Discharges IED), favorecendo a inclusão de sinais do EEG de menor destaque. Além dessa vantagem, ele ainda permite incluir modelos do sinal BOLD com diferentes latências, aumentando a abrangência da variabilidade das respostas encontradas em pacientes com epilepsia. A eficiência do ICA-GLM também foi comparado à do GLM e dKLg nos exames de EEG-fMRI. Embora os resultados tenham demonstrado a robustez do GLM, em alguns pacientes o dKLg foi mais eficiente para localizar regiões concordantes que não foram detectadas pelo GLM. Ainda, em boa parte dos casos o ICA-GLM detectou regiões mais extensas e com maior valor estatístico, quando comparado ao GLM. De forma geral, nota-se que o dKLg e ICA-GLM podem ser ferramentas complementares importantes ao GLM, aumentando a sensibilidade dos exames de EEG-fMRI como um todo. Outra etapa importante nas avaliações de EEG-fMRI em pacientes com epilepsia tem sido a utilização de imagens de fontes elétricas (Electrical Source Imaging ESI). Neste trabalho, os mapas de ESI foram obtidos por dois métodos de solução inversa distribuída nunca usados no cenários da EEG-fMRI: Bayesian Model Averaging (BMA) e constrained Low Resolution Electromagnetic Tomography (cLORETA). Além da construção dos mapas de ESI, avaliamos a utilidade de combinar as técnicas de ESI e de EEG-fMRI para promover a diferenciação entre fontes primárias e de propagação temporal. Essa análise permitiu avaliar a concordância entre as regiões detectadas pelo ESI e EEG-fMRI e diferenciar as respostas BOLD relacionadas aos componentes iniciais e posteriores da IED. Embora os resultados ainda sejam preliminares para eleger qual método seria mais eficiente (cLORETA ou BMA), a distância encontrada entre o máximo ESI e o cluster de EEG-fMRI mais próximo foi consistentemente similar, em ambos, com os dados recentes da literatura.<br>Functional magnetic resonance imaging (fMRI) and combined EEG-fMRI usually rely on the successful detection of Blood Oxygenation Level Dependent (BOLD) signal. Typically, the analysis of both fMRI and EEG-fMRI are based on the General Linear Model (GLM) that aims at localizing the BOLD responses associated to an a priori model. However, the responses are not always canonical, as is the case of those from patients, which may reduce the reliability of the results. Therefore, the first objective of the present study was to explore the usage of classical methods, such as the GLM, and to propose alternative strategies to the analysis of fMRI and combined EEG-fMRI. A first method developed was based on the computation of the generalized Kullback-Leibler distance (gKLd), which does not require the use of an a priori model. Simulated data was used to allow quantitative comparison between the gKLd and GLM under different response conditions such as the signal to noise ratio and delay. The gKLd was then tested on real data, first from 14 asymptomatic subjects, submitted to classical motor and auditory fMRI protocols. The results demonstrate that under these conditions the GLM and gKLd are equivalent. The same strategy was applied to 02 patients with unilateral carotid stenosis. Now the dKLg was capable of detecting the expected bilateral BOLD responses that were not detected by the GLM, as a consequence of the response delay imposed by the stenosis. Those comparisons were now extended to the evaluation of EEG-fMRI exams from 45 patients with epilepsy. For this data set, an additional method was used, based on the use of Independent Component Analysis (ICA), which was called ICA-GLM. It allows extracting semi-automatically the amplitude, duration and topography of EEG interictal Epileptiform Discharges (IED), favoring the use of less prominent signals. Moreover, it also allows the use of BOLD response models with different delays, expanding the variability of the responses to be detected in patients with epilepsy. ICA-GLM was also compared to GLM and dKLg in these EEG-fMRI evaluations. Although in general the results have demonstrated the robustness of the GLM, dKLg was more efficient in detecting the responses from some pacients, while the ICA-GLM mostly detected broader regions with more significant results when compared to GLM. In general, dKLg and ICA-GLM seem to offer an important complementary aspect to the GLM, increasing its sensibility in EEG-fMRI as a whole. Another important aspect of EEG-fMRI applied to patients with epilepsy has been the inspection of Electrical Source Imaging (ESI) to evaluate some dynamical aspects of the IED. Herein, ESI maps were obtained from two inverse distributed solutions that were not applied so far to EEG-fMRI: Bayesian Model Averaging (BMA) and constrained Low Resolution Electromagnetic Tomography (cLORETA). Besides, we also evaluated the combined information from ESI and EEG-fMRI in order to differentiate from primary sources to temporal propagation of the signal. Such analysis allowed us to inspect for the correspondence between regions detected by ESI e EEG-fMRI and to separate BOLD signals whose sources are related to the initial and later components of the IED. Although the results are preliminary to determine which ESI method (cLORETA or BMA) is more efficient, the distance between the maximum ESI and the closest EEG-fMRI cluster was consistently similar with those reported in the literature.

Abstract:
This chapter describes methods to analyze the scalp electric field recorded with multichannel electroencephalography (EEG). With advances in high-density EEG, systems now allow fast and easy recording from 64 to 256 channels simultaneously. Pattern-recognition algorithms can characterize the topography of scalp electric fields and detect changes in topography over time and between experimental or clinical conditions. Methods for estimating the sources underlying the recorded scalp potential maps have increased the spatial resolution of EEG. The use of anatomical information in EEG source reconstruction has increased the precision of EEG source localization. Algorithms of functional connectivity applied to the source space allow determination of communication between large-scale brain networks in certain frequencies and identification of the directionality of this information flow and detection of crucial drivers in these networks. These methods have boosted the use of EEG as a functional neuroimaging method in experimental and clinical applications.

Abstract:
The Southeast Coast Network (SECN), with the support of the National Park Service (NPS) Vegetation Mapping Inventory Program, described and mapped vegetation at Cumberland Island National Seashore (CUIS). This mapping effort was accomplished through collaboration with the Southeast regional office of NatureServe (Raleigh/Durham, N.C.). The mapping area was 15,163.4 hectares (ha), encompassing the entire boundary of the seashore plus an additional buffered area. NatureServe ecologists identified plant associations for the seashore and a remote sensing specialist from the Southeast Coast Network conducted the vegetation mapping using 1:12,000-scale, color-infrared aerial photography and digital orthophotography. NatureServe collected vegetation and environmental data from 85 vegetation classification plots, and the remote sensing specialist assessed 60 observation points. Interns from the Student Conservation Association (SCA) and consultants from the Atkins consulting firm conducted an accuracy assessment (AA), which entailed sampling 712 points. Fieldwork and mapping were completed between 2005 and 2015. A total of 43 map classes were developed to map the vegetation and general land cover of Cumberland Island National Seashore and surroundings, including the following: 32 map classes representing natural/semi-natural vegetation at the association level in the National Vegetation Classification System (NVCS), 1 map class representing cultural vegetation (e.g., developed) in the NVCS, and 10 map classes representing non-vegetated units (e.g., open water bodies, buildings, roads). Features were interpreted using 1:12,000 scale digital color-infrared aerial photography (flown 01 May 2011) through heads-up-digitizing in ArcGIS (Version 10.0, © 2010 Environmental Systems Research Institute, Redlands, California). Polygons were mapped to a 0.5-hectare minimum mapping unit (MMU). A geodatabase containing various feature class layers and tables was constructed to show the locations of vegetation types and general land cover (vegetation map), vegetation plot samples, AA sites, project boundary extent, and aerial photographic centers. The feature class layer for the CUIS vegetation map provides 1,005 polygons of detailed attribute data covering 15,163.4 hectares, with an average polygon size of 144.7 hectares. Of the area mapped, 816 polygons (81% of all polygons) represent natural/semi-natural vegetation types in the NVCS, encompassing 9,542.8 hectares (62.9%) of the total map extent. Summary reports generated from the vegetation map layer indicate that the combined group Live Oak – (Cabbage Palmetto) Forest Alliance / Southeastern Florida Maritime Hammock dominates the vegetated landscape (101 polygons covering 3,746.6 ha). The combined group Southern Atlantic Coast Salt Marsh / Salt Flat (Swampfire Type) also covers a considerable portion of the seashore (92 polygons totaling 3,678.8 ha). A thematic accuracy assessment study was conducted on the nine map classes in the boundary of the seashore that represent floristic types within the NVCS. Results present an overall accuracy of 83.9% (Kappa statistic = 64.2%) based on data from 712 AA sites.

Full text
Abstract:
As is true for all crops, production of Citrus fruit is limited by traits whose characteristics are the products of many genes (i.e. cold hardiness). In order to modify these traits by marker aided selection or molecular genetic techniques, it is first necessary to map the relevant genes. Mapping of quantitative trait loci (QTLs) in perennial plants has been extremely difficult, requiring large numbers of mature plants. Production of suitable mapping populations has been inhibited by aspects of reproductive biology (e.g. incompatibility, apomixis) and delayed by juvenility. New approaches promise to overcome some of these obstacles. The overall objective of this project was to determine whether QTLs for environmental stress tolerance could be effectively mapped in the perennial crop Citrus, using an extensive linkage map consisting of various types of molecular markers. Specific objectives were to: 1) Produce a highly saturated genetic linkage map of Citrus by continuing to place molecular markers of several types on the map. 2) Exploiting recently developed technology and already characterized parental types, determine whether QTLs governing cold acclimation can be mapped using very young seedling populations. 3) Determine whether the same strategy can be transferred to a different situation by mapping QTLs influencing Na+ and C1- exclusion (likely components of salinity tolerance) in the already characterized cross and in new alternative crosses. 4) Construct a YAC library of the citrus genome for future mapping and cloning.

Natural Resources Canada/CMSS/Information Management, 2021. http://dx.doi.org/10.4095/329093.

Abstract:
Australia's and China's resources (e.g. Olympic Dam Cu-U-Au-Ag and Bayan Obo REE deposits) highlight how discovery and mining of iron oxide copper-gold (IOCG), iron oxide±apatite (IOA) and affiliated primary critical metal deposits in metasomatic iron and alkali-calcic (MIAC) mineral systems can secure a long-term supply of critical metals for Canada and its partners. In Canada, MIAC systems comprise a wide range of undeveloped primary critical metal deposits (e.g. NWT NICO Au-Co-Bi-Cu and Québec HREE-rich Josette deposits). Underexplored settings are parts of metallogenic belts that extend into Australia and the USA. Some settings, such as the Camsell River district explored by the Dene First Nations in the NWT, have infrastructures and 100s of km of historic drill cores. Yet vocabularies for mapping MIAC systems are scanty. Ability to identify metasomatic vectors to ore is fledging. Deposit models based on host rock types, structural controls or metal associations underpin the identification of MIAC-affinities, assessment of systems' full mineral potential and development of robust mineral exploration strategies. This workshop presentation reviews public geoscience research and tools developed by the Targeted Geoscience Initiative to establish the MIAC frameworks of prospective Canadian settings and global mining districts and help de-risk exploration for IOCG, IOA and affiliated primary critical metal deposits. The knowledge also supports fundamental research, environmental baseline assessment and societal decisions. It fulfills objectives of the Canadian Mineral and Metal Plan and the Critical Mineral Mapping Initiative among others. The GSC-led MIAC research team comprises members of the academic, private and public sectors from Canada, Australia, Europe, USA, China and Dene First Nations. The team's novel alteration mapping protocols, geological, mineralogical, geochemical and geophysical framework tools, and holistic mineral systems and petrophysics models mitigate and solve some of the exploration and geosciences challenges posed by the intricacies of MIAC systems. The group pioneers the use of discriminant alteration diagrams and barcodes, the assembly of a vocab for mapping and core logging, and the provision of field short courses, atlas, photo collections and system-scale field, geochemical, rock physical properties and geophysical datasets are in progress to synthesize shared signatures of Canadian settings and global MIAC mining districts. Research on a metamorphosed MIAC system and metamorphic phase equilibria modelling of alteration facies will provide a foundation for framework mapping and exploration of high-grade metamorphic terranes where surface and near surface resources are still to be discovered and mined as are those of non-metamorphosed MIAC systems.

Abstract:
In this report, we demonstrate how an interdisciplinary team of computer science and learning sciences researchers utilize an adapted conjecture mapping tool during a collaborative problem-solving session. The session is documented through an edited “Dialogue” format, which captures the process of conjecture map construction and subsequent reflection. We find that creating the conjecture map collaboratively surfaces a key tension: while learning sciences theory often highlights the nuanced and complex relational nature of learning, even the most cutting-edge computing techniques struggle to discern these nuances. Articulating this tension proved to be highly generative, enabling the researchers to discuss how considering impacted community members as a critical “part of the solution” may lead to a socio-technical tool which supports desired learning outcomes, despite limitations in learning theory and technical capability. Ultimately, the process of developing the conjecture map directed researchers towards a precise discussion about how they would need to engage impacted community members (e.g., teachers) in a co-design process.

Abstract:
This report sets out to map the different guidance documents available on how to work most effectively with civil society in the delivery of international aid in ways that deepen democracy and advance the rights of marginalised or excluded groups. It includes a review of guidelines published by other key international development funders and implementors written for their own teams, an overview of guidance provided for DAC members within OECD countries and policy papers on cooperation between the state and CSOs. It looks primarily at documents produced in the last ten years, between 2011 and 2021 and includes those related to cooperation on specific issues (such as drugs policy or human rights, as well as those that deal with specific countries or regions (such as Europe or the MENA region). The majority of documents identified are written by government aid departments (eg USAID, Norad) but there are one or two produced by umbrella civil society organisations (such as Bond) or international legal think tanks (such as ICNL, the International Centre for Not for Profit Law). There was a remarkable consistency between the issues Millican addressed in the different documents although their size and length varied between outline guidance on 2 – 3 pages and a comprehensive (62 page) overview that included definitions of civil society, range of organisations, reasons for collaborating, mechanisms for financing, monitoring and ensuring accountability and challenges in and guidance on the ways in which donors might work with CSOs.

Abstract:
The purpose of this Coastal and Hydraulics Engineering Technical Note (CHETN) is to highlight emerging tools for inlet geomorphic mapping and describe the workflows used to implement the tools. The Coastal Inlets Research Program (CIRP) maintains the US Coastal Inlets Atlas, which houses technical information (e.g., physical processes, navigation channel position, federal authorization for management purposes) on tidal inlets. Future expansion of the Atlas should include ready-made products that address a call from coastal inlet managers and practitioners to map inlet geomorphic change and features more accurately. The methods and workflows demonstrated in this document represent the first step towards expanding the US Coastal Inlets Atlas.

Full text
Abstract:
Early childhood care and development (ECCD) discourse, policy, and research have understandably focused on parents—their roles, knowledge, practices, and lived experiences. However, it truly “takes a village” to raise a child, particularly in an intergenerational, communal society like the Philippines, where both historical and future trends indicate a greater involvement of various “significant others” in the pag-aalaga (i.e., care or nurturing) of children. This report examines how Filipino parents approach early childhood development, emphasizing the central roles of various actors—parents, siblings, grandparents, domestic helpers (yayas, kasambahays), and community members (e.g., barangay health workers)—in shaping children's early development. Inspired by 17 key informant interviews and a review of the social sciences literature, we map the different participants in ECCD and propose ways to leverage their involvement to improve child health and education outcomes.

Full text
Abstract:
The microscopic composition of thirteen samples of epidote related to porphyry Cu mineralization was mapped using laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) at the Geological Survey of Canada. The objective of this research is to improve the indicator mineral method of mineral exploration in glaciated terrains by utilizing the trace element composition of epidote. Six bedrock samples from porphyry Cu deposits of south-central British Columbia (Gibraltar, Mount Polley and Woodjam), three bedrock samples from the Nicola Group located close (&amp;amp;lt;2 km) from the intrusions host of porphyry mineralization and afar (12 km), and four epidote grains from two till samples, one at Gibraltar and a second one at Mount Polley, were analyzed. Backscattered electron (BSE) images and the LA-ICP-MS maps show an heterogeneous distribution of Fe and Al in epidote following complex and mottled patterns and consistent zoning typically with high Fe and low Al concentrations in the core progressing to low Fe and high Al concentrations in the rim. Trace elements are heterogeneously distributed in epidote following the Fe/Al zoning in some samples. Evidence of late infiltration of trace elements (e.g. Cu, Zn, and REE) along fractures in epidote is observed in some samples. The variability in epidote composition is thought to be related to the changing conditions during its crystallization including oxidation state, pH, oxygen fugacity, fluid composition, temperature and pressure. Multiple LA-ICP-MS spot analyses need to be conducted on this mineral to fully evaluate its composition as an indicator mineral of porphyry Cu mineralization.
