Abstract:

Sediment petrography and heavy mineral analysis represent two key techniques to decipher the pieces of information stored in the sedimentary record, shedding light on source rocks compositon, weathering conditions and paleodrainages. Traditionally, even though orogenic detritus has always received large attention, orogenic provenance has been recognized as “composite”, thus preventing clear classification. Notwithstanding the composite nature of collision orogens, the detrital fingerprints of neometamorphic axial belts, largely experiencing strong exhumation and erosion, can be regarded as th

Abstract:

The timing of the Alpine deformation in the Central Southern Alps (CSA or Orobic Alps) has always been a debated topic, since the scarcity of reliable absolute age constraints has prevented an accurate chronological reconstruction of the evolution of this sector of the European Alps. In this work, detailed structural analyses performed in different areas of the CSA allowed us to distinguish different compressive features within both the crystalline basement and the sedimentary cover. The integration of these field data with new isotopic data provides time constraints for the reconstruction o

Uplift of the Teton Range is primarily controlled by displacement across the range-front Teton normal fault. The Tetons comprise the footwall block while the hanging wall encompasses Jackson Hole valley and a portion of the Snake River. Relative to the rest of the Rocky Mountains, the Tetons experienced the majority of uplift very recently, substantiating the need for a detailed investigation integrating structural analysis and bedrock thermochronometry. New low-temperature cooling ages are documented in three vertical transects across the Teton Range and at low elevations parallel to the T

Abstract:

The integration of low-temperature thermochronometers, including apatite and zircon (U-Th)/He (AHe, ZHe) and apatite fission-track (AFT) methods, allows for a quantification of the thermal history experienced by rocks as they heat and cool through upper crustal temperature regimes (<200°C). Whereas these methods are practical in geologic terranes that have undergone rapid cooling, application to strata with protracted cooling histories is complicated by the enhanced role of grain-specific parameters (volume, chemistry, radiation damage) on the kinetics of helium diffusion and fission track ann

The study of the Cretaceous–Cenozoic evolution of the North Patagonian Andes represents a great opportunity to investigate the effects of coupling between deep lithospheric processes and near-surface deformation.

Thus, this plate margin results in a more complex conﬁguration with respect to the simpliﬁed notion of “Andean-type” subduction system. Being located in the retro

Abstract:

The evolution of intracontinental mountain ranges represent a unique challenge in our understanding of the Earth’s history. One of the largest of these intracontintal mountain ranges on Earth is the Tian Shan in Central Asia. The crustal architecture of the Tian Shan formed during the closure of the Palaeo-Asian Ocean in the Palaeozoic and underwent multiple reactivations in response to distant tectonic events at the Eurasian plate margin, to give rise to the modern expression of the Tian Shan we see today. Most of the previous thermochronological studies in the Tian Shan focused on the core o

This model suggests that the development of the fold and thrust propagates southwardly. With the cessation of active folding and thrusting during the collision, northern Taiwan is now undergoing post-collisional extension, followed by the eruption

U-Pb dating of calcite in tectonic veins represents a new method to potentially directly date brittle deformation events (Roberts and Walker, 2016).

The anticline is located to the northwest of the Sichuan Basin within the Songpan-Ganzi orogen. Because the fold axis of the anticline is subparallel to the direction of the surface compression, buckling is unlikely the mechanism responsible for the growth of the Danba Anticline. We suspect that the formation of the Danba Anticline in Cenozonic period may be related to the middle crustal flow. The sharp change in GPS velocity field near the Sichuan Bas

Abstract:

Apatite fission track data show a gradual decrease in age (&sim;30 Ma to &sim;15 Ma) from north to the south in the eastern SerranIa del Interior, northeastern Venezuela. Based on a previous study, a model for the tectonic evolution of the eastern SerranIa is proposed in which two stages of deformation occurred. Stage 1 (45 Ma--20 Ma) involves the internal deformation of fault blocks. Stage 2 (20 Ma--12 Ma) involves envelopment thrusting, doubling the thickness of the thrust sheet. Shortening within the SerranIa del Interior ceased at 12 Ma. In stage 1, cooling and exhumation rates were 5.8&de

Abstract:

The formation and evolution of metamorphic core complexes has been widely studied using low temperature thermochronometry methods. Interpretation of these data has historically occurred through the lens of the traditional slip rate method which provides a singular rate that unroofing occurs at temporally as well as spatially, and assumes unroofing is dominated by motion on a single master detachment fault. Recently, several new studies have utilized (U-Th)/He ages with a higher spatial density and greater nominal precision to suggest a late-stage rapid increase in the rate of unroofing. This a

A large number of geological studies around the globe have used radiogenic isotopes in accessory minerals to thoroughly investigate upper and lower crustal processes. Minerals such as zircon, monazite, rutile and apatite are some examples of high and low temperature geochronometers which have been applied to various geological problems. Heavy mineral geochronometers have been commonly used to date high temperature igneous and metamorphic processes.

Previous work has indicated that the central Gawler Craton was largely exhumed during the Carboniferous as a far-field effect of the Alice Springs Orogeny. Besides this widespread exhumation event, localised Mesozoic and Tertiary thermal events have been documented for the central Gawler Craton as well. The extent of these events into the northern Gawler Craton is not well understood as low-temperature thermochronological data is lacking for this region.
