Carbon geo sequestration (CGS) is considered one of the promising approaches to reducing anthropogenic greenhouse gas emissions into the environment. Furthermore, Underground Hydrogen Storage (UHS) has been also identified as a viable solution to effectively stored hydrogen in geological formations. The underground storage of hydrogen (UHS) project has the potential to overcome the supply and demand imbalance by a subsequent withdrawal during periods of renewable energy shortage. Depleted petroleum reservoirs and deep saline aquifers are considered favorable candidates for long-term H2 and CO2 storage. H2 and CO2 become trapped in the reservoir by various physical and chemical mechanisms, and these mechanisms mainly include residual trapping and structural trapping, dissolution, and mineralization trapping. The wettability of rock minerals for storage gas in the presence of brine is a significant physicochemical factor that largely affects the trapping mechanism. The reservoir formations naturally contain small concentrations of water-soluble organic components in particular humic acid (HA). These organic components in formations also assist the growth of various natural organotrophic microorganisms. While the earlier investigations suggest the impact of organic matter and microorganisms on wetting behaviour for enhanced oil recovery applications, we here argue that these organic matter and microorganisms have a significant effect on the CO2 and H2 wettability of the subsurface formations as well. Therefore, we prepared organic acid and bacteria-treated surfaces, and the effects of these treated surfaces on the H2 and CO2 wettability of subsurface reservoirs were evaluated via advancing and receding contact angle measurements, streaming zeta potential, and NMR techniques, at various organic acid concentrations, high pressures (up to 25 MPa), elevated temperatures (up to 333 K) and brine salinity (up to 0.3 M NaCl), that simulate the subsurface reservoir conditions. The surface characterizations were examined by high-resolution scanning electron microscopy (SEM) and atomic force (AFM) microscopy imaging while other characterization tools (e.g. TOC, EDX, and FTIR) were also implemented to gain a broader insight into the observed wetting behaviour. Our results demonstrate that water-soluble organic acid concentration significantly changes rock wettability from water-wet (0-50o) towards CO2-wet (90-110o). Furthermore, a strong correlation exists between surface adsorption of organic acid and streaming potential coefficient, where the amount of residual water saturation decreases in organic acid aged cores – suggesting the presence of organic acid changes wettability towards CO2 wet in pores. The low organic content WA basalt was initially water-wet but with increasing pressure, it was also converted into a completely CO2-wet at pressures exceeding 15 MPa and 323 K. The results of bacteria-treated quartz surfaces suggest that (1) bacterial growth is prominent on the quartz surfaces with organic matter and, (2) the originally hydrophilic surfaces tend to become less hydrophilic while the hydrophobic surfaces turn less hydrophobic in the presence of microorganisms. The results of this investigation provide a fundamental understanding of H2 and CO2 wettability alteration in the subsurface microbial environment along with organic acid, thus, having implications for de-risk the large-scale carbon geo-sequestration (CGS) and underground hydrogen storage (UHS) projects.

[Truncated abstract] The Neoarchean (2800 to 2600 Ma) Eastern Goldfields Superterrane (EGST) comprises elongated belts of deformed and metamorphosed volcanic and sedimentary rocks intruded by granitoids. The Superterrane is made up of five distinct tectonostratigraphic terranes. From west to east these are the Kalgoorlie, Gindalbie, Kurnalpi, Laverton and Duketon Terranes. The Kalgoorlie Terrane is characterised by 2720 to 2680 Ma marine mafic-ultramafic volcanic successions interlayered with, and overlain by, 2710 to 2660 Ma dominantly trondhjemite-tonalite-dacite (TTD) dacititic volcaniclastic rocks (Black Flag Group). The adjacent Gindalbie and Kurnalpi terranes are characterised by 2720 to 2680 Ma calc-alkaline volcanic successions representing oceanic island arcs. To the west of the EGST, the Youanmi Terrane is characterised by older, dominantly 3000 to 2900 Ma greenstone rocks and complex granitoid batholiths derived from older crustal sources. The southern Kalgoorlie Terrane comprises five elongate NNW-trending tectono-stratigraphic domains. Three principal marine komatiitic to basaltic suites, collectively referred to as the Kambalda Sequence, are present, including the wellpreserved massive to pillowed Lower and Upper Basalt Sequences, separated by the Komatiite Unit, as well as numerous dyke suites. The Lower Basalt Sequence comprises the Woolyeenyer Formation, Lunnon, Wongi, Scotia, Missouri Basalts and Burbanks and Penneshaw Formations, whereas the Upper Basalt Sequence contains the Paringa, Coolgardie, Big Dick, Devon Consols, Bent Tree, and Victorious basalts. ... Instead, the data suggest that discrete PGE-bearing phase (s) fractionated from the basaltic magmas. Such phases could be platinum group minerals (PGM; e.g. laurite) and/or alloys, or discrete PGE-rich nuggets. In summary, data on the three magmatic sequences record decompression melting of three distinct mantle sources: (1) long-term depleted asthenosphere for prevalent depleted tholeiitic and komatiitic basalts, and komatiites; (2) long-term enriched asthenosphere for Paringa Basalts and similarly enriched rocks; and (3) shortterm enriched continental lithospheric mantle (CLM) for HREE and Al-depleted dykes. Some of these rocks were contaminated by TTD-type melts. Taken with the existing geophysical and xenocrystic zircon data, the most straightforward interpretation is eruption of a zoned mantle plume at the margin of rifted continental lithosphere. The Kalgoorlie Terrane extensional basin was subsequently tectonically juxtaposed with the adjacent arc-like Gindalbie and Kurnalpi Terranes at approximately 2660 Ma at the start of orogeny in a Cordilleran-style orogen to form the EGST. Collectively, uncontaminated basalts have Nb/Th of 8-16, compared to 8-12 reported for the Lunnon basalts in a previous study. To a first approximation these asthenosphere melts are complementary to average Archean upper continental crust with Nb/Th =2, consistent with early growth of large volumes of continental crust rather than models of steady progressive growth.

The Neoproterozoic (815.4 ± 4.3 Ma) Aries kimberlite intrudes the King Leopold Sandstone and the Carson Volcanics in the central Kimberley Basin, northern Western Australia. Aries is comprised of a N-NNE-trending series of three diatremes and associated hypabyssal kimberlite dykes and plugs. The diatremes are volumetrically dominated by massive, clast-supported, accidental lithic-rich kimberlite breccias that were intruded by hypabyssal macrocrystic phlogopite kimberlite dykes and plugs with variably uniform- to globular segregationary-textured groundmasses. Lower diatremefacies, accidental lithic-rich breccias probably formed through fall-back of debris into the vent with a major contribution from the collapse of the vent walls. These massive breccias are overlain by a sequence of bedded volcaniclastic breccias in the upper part of the north lobe diatreme. Abundant, poorly-vesicular to nonvesicular, juvenile kimberlite ash and lapilli, with morphologies that are indicative of phreatomagmatic fragmentation processes, occur in a reversely-graded volcaniclastic kimberlite breccia unit at the base of this sequence. This unit and overlying bedded accidental lithic-rich breccias are interpreted to be sediment gravity-flow deposits (including possible debris flows) derived from the collapse of the crater walls and/or tephra ring deposits that surrounded the crater. ... This Fe-enrichment may have resulted from Fe-Mg exchange with olivine during slow cooling of the peridotite host rocks. Textures reflecting the cooling history of some mantle xenoliths are preserved in the form of fine exsolution rods of aluminous spinel in diopside and zircon in rutile grains in aluminous spinel- and rutile-bearing serpentinised ultramafic xenoliths, respectively. These textures suggest nearly isobaric cooling of host rocks in the lithospheric mantle, and indicate that at least some aluminous spinel in spinel-facies peridotites formed through exsolution from chromian 4 diopside. Episodes of Fe-Ti-rich metasomatism in the spinel-facies Kimberley mantle are the likely source of high-Ti phlogopite-biotite + rutile and Ti, V, Zn, Ni-enriched aluminous spinel ± ilmenite associations in several ultramafic xenoliths. U-Pb SHRIMP 207Pb/206Pb zircon ages for one granite (1851 ± 10 Ma) and two serpentinised ultramafic xenoliths (1845 ± 30 Ma; 1861 ± 31 Ma) indicate that the granitic basement and lower crust beneath the central Kimberley Basin are at least Palaeoproterozoic in age. However, Hf-isotope analyses of the zircons in the ultramafic xenoliths suggest that the underlying lithospheric mantle is at least late Archaean in age.

Humanity's relationship with rocks is a long-standing one. Belk (1995, p.2) describes archaeological evidence of early assemblages of rocks found in Cro-Magnon caves that would not be out of place in contemporary rock-collections. Historically, apart from being used as material for tools and buildings. rocks were also used for magical, pharmaceutical and decorative purposes. During the Renaissance and Enlightenment, the practice of collecting rocks became associated with the sense of discovery and the colonial expansion of western European civilization across world, and with advances in mining, science and industry. It is a practice that continues through to the present day. This thesis is an ethnography that asks contemporary rock collectors: why do they collect rocks? How do they collect rocks? And, how do they talk about them? Adapting Foucault's theoretical framework on discourse (1970) and utilising positions on collecting put forward by Baudrillard ( 1994), Belk ( 1995), Benjamin (1999), and others, the thesis analyses interviews and images of rock-collectors and their collections and puts forward a snapshot of the discourse of rocks and rock-collecting as currently practiced. The thesis's theoretical framework is first tested on texts of popular culture on rocks and rock-collecting to locate and identify the statements and discursive formations that make up the discourse, and then it is applied to the interviews of contemporary collectors talking about their collections. While some rock collectors practice alone and their approaches may appear idiosyncratic, others, sharing knowledge and experience, practice in a club environment. The collectors' approaches to rock collecting range from the taxonomic and scientific to the aesthetic and utilitarian, personal and historical, and, for some, to the metaphysical. In Australia some aspects of rock-collecting are allied to prospecting and mining. For some collectors the rocks are souvenirs, and are connected to travel. For other collectors rock-collecting is associated with understandings of nature, time and space. The interviews reveal that in a consumer society rocks are also commodities, with many of the collectors not only acquiring their rocks in the field, but also buying what they cannot find, or trade, for their collection. The analysis of the collectors' interviews demonstrates that the discourse does not stand as an isolated figure, but shares statements and configurations of statements with many other discourses in the field of knowledge, including science, history, archaeology and metaphysics. The interviews also illustrate how discourse and their associated practices are subject to external and internal rules and regulations, imposed by the State, and by institutions of academia and cultural and scientific practices, such as museums and universities. Some collectors aspire to emulate museums, and wish to share with others knowledge about to their collection through exhibition. The variety of themes and practices found in the interviews reinforce Foucault's proposition that within a discourse statements and configurations of statements may arise that are incompatible and form diffractions in the discourse. While apparently incompatible themes, variations and differences exist within the discourse, the analysis of the interviews and the conclusion of the thesis underscore the underlying unities of the discourse of rocks and rock-collecting.

This study assessed the geochemical characteristics of lignite and other waste rock of the future South Jimblebar Iron Ore Mine in Western Australia. Results indicated that lignite of CzD 2 and black shale of MU stratigraphic units were potentially acid forming (PAF) materials and relatively enriched in certain elements of environmental significance. In contrast, non-carbonaceous mudstones were non-acid forming (NAF). These findings indicate potential for acid mine drainage generation that will requires specific waste rock management.

International reference materials were employed to investigate the efficacy of ICP-MS for determination of selenium in rocks. Results indicate that significant inaccuracies may occur in the reported Se content of rocks, particularly those containing high Fe and Al, using routine procedures employed by commercial laboratories in trace element analysis. Analysis of waste rocks from three Pilbara iron ore mines revealed significant potential sources of selenium contamination with lignite and carbonaceous shales particularly enriched in selenium.

Samples of every rock type present along a traverse through the Jack Hills belt were examined and processed for zircon, monazite and xenotime isotopic study. Zircon U-Pb ages range from 1618±22 Ma to 4381±5 Ma, confirming the presence of both Archean and Proterozoic successions. Lutetium-Hf data for Hadean zircons imply a primitive source that was reworked with little juvenile input from the mantle. Monazite data confirm that the Archean rocks were metamorphosed at 2.65 Ga.

Two groups of mafic volcanic rocks and three types of granitoids have been identified in the Yalgoo area of Western Australia. Granodiorite records ages of ~2760 Ma and biotite monzogranite ages of 2636 Ma. A 1.85 Ga dolerite dyke is the first Paleoproterozoic dyke identified from the Yilgarn Craton. An indirect age of ~2.63 Ga is inferred for gold mineralization. Geochemical data indicate formation in a continental marginal arc with traces of Hadean crust.
