Fault Slip and Exhumation History of the Willard Thrust Sheet, Sevier Fold‐Thrust Belt, Utah: Relations to Wedge Propagation, Hinterland Uplift, and Foreland Basin Sedimentation [PDF]
Zircon (U‐Th)/He (ZHe) and zircon fission track thermochronometric data for 47 samples spanning the areally extensive Willard thrust sheet within the western part of the Sevier fold‐thrust belt record enhanced cooling and exhumation during major thrust ...

Abstract The Kosi River watershed captures the major lithotectonic units, structures, and characteristic climatic conditions found along the Himalaya. Therefore, this setting provides a useful location to investigate the respective influences of tectonics and climate in eroding bedrock and driving landscape evolution.

Improved spatial resolution of elemental maps through inversion of LA-ICP-MS data [PDF]
Laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) provides the spatial distribution of elements within crystals and therefore can constrain the rates of geological processes.

Abstract A limitation in our understanding of the geodynamics of orogenies is the difficulty in resolving the spatial variations in long‐term processes such as exhumation of the crust. Although geodesy can record ground motions to millimeter‐scale precision at high spatial and temporal resolutions, these observations only cover a small fraction of the ...

Low-temperature thermochronology, including fission track (FT) and (U–Th–Sm)/He thermochronometry, has been widely used to constrain the exhumation history of orogenic systems over timescales of 106–108 years.

Exhumation of the Inyo Mountains, California: Implications for the Timing of Extension along the Western Boundary of the Basin and Range Province and Distribution of Dextral Fault Slip Rates across the Eastern California Shear Zone [PDF]
New geologic mapping, tectonic geomorphologic, 10Be terrestrial cosmogenic nuclide, and (U-Th)/He zircon and apatite thermochronometric data provide the first numerical constraints on late Cretaceous to late Quaternary exhumation of the Inyo Mountains ...

We show that including provenance ages in thermochronometry modelling is key to arriving at a single consistent model explaining our complex dataset. With our approach, we reconcile previous studies on the northern Swiss Molasse Basin and contribute to the discussion of exhumation drivers. ABSTRACT Dispersed single‐grain ages are a common phenomenon in

The thermal history of the Western Irish onshore [PDF]
We present here a low-temperature thermochronological study that combines the apatite fission-track and (U + Th)/He dating methods with a pseudo-vertical sampling approach to generate continuous and well-constrained temperature–time histories from the ...

The Evolution of the Cocos‐North America‐Caribbean Triple Junction From Detrital Zircon Analysis
Abstract The tectonic framework and Cenozoic evolution of the Cocos–North America–Caribbean (Co–NA–Ca) triple junction remain subjects of major geological importance due to their complexity and regional impact. New U–Pb zircon geochronology of detrital sediments and detailed structural and geomorphic mapping from southern Chiapas, Mexico, provide ...

Abstract Global cooling during the Late Cenozoic led to periodic glaciations in many mountain regions. The repeated waxing and waning of glaciers and ice sheets resulted in continuously changing erosion regimes that modified the underlying topography.
