Decoding low-temperature thermochronology signals in mountain belts: modelling the role of rift thermal imprint into continental collision

open access: yesBSGF - Earth Sciences Bulletin, 2021
Resolving the timing of initiation and propagation of continental accretion associated with increasing topography and exhumation is a genuinely challenging task using low-temperature thermochronology.

The Rise and Fall of Laramide Topography and the Sediment Evacuation From Wyoming

open access: yesGeophysical Research Letters, 2023
The modern topography within the Laramide region consists of high‐relief ranges and high‐elevation low‐relief (HELR) surfaces separated by intraforeland basins.

Tectonic history of the South Tannuol Fault Zone (Tuva region of the northern Central Asian Orogenic Belt, Russia) : constraints from multi-method geochronology [PDF]

open access: yes, 2020
In this study, we present zircon U/Pb, plagioclase and K-feldspar Ar-40/Ar-39 and apatite fission track (AFT) data along the South Tannuol Fault Zone (STFZ).

Record of Crustal Thickening and Synconvergent Extension from the Dajiamang Tso Rift, Southern Tibet

open access: yesGeosciences, 2021
North-trending rifts throughout south-central Tibet provide an opportunity to study the dynamics of synconvergent extension in contractional orogenic belts.

Structural Style and Kinematic History of the Colombian Eastern Cordillera

open access: yesFrontiers in Earth Science, 2021
Fold-and-thrust belts and their associated structures are among the most common geological features of convergent margins. They provide significant information about crustal shortening and mountain-building processes.

Enhanced Quaternary Exhumation in the Central Three Rivers Region, Southeastern Tibet

open access: yesFrontiers in Earth Science, 2021
The roles of tectonics and climate in the global increased erosion rates during the Quaternary have been the subject of active debate. The Three Rivers Region, strongly influenced by continental convergence between India and Eurasia and change in Asian ...

Implementation of an Alpha Damage Annealing Model for Zircon (U‐Th)/He Thermochronology With Comparison to a Zircon Fission Track Annealing Model

open access: yesGeochemistry, Geophysics, Geosystems, 2021
Radiation damage exerts a fundamental control on He diffusion in zircon, which manifests as correlations between (U‐Th)/He date and effective uranium concentration. These correlations can be exploited with modeling to explore long‐term thermal histories.

Reconciling Spatial and Temporal Patterns of Cenozoic Shortening, Exhumation, and Subsidence in the Southern Bolivian Andes

open access: yesFrontiers in Earth Science, 2021
The Bolivian Andes are an archetypal convergent margin orogen with a paired fold-thrust belt and foreland basin. Existing chronostratigraphic constraints highlight a discrepancy between unroofing of the Eastern Cordillera and Interandean Zone fold-thrust

Low-temperature thermochronology and thermokinematic modeling of deformation, exhumation, and development of topography in the central Southern Alps, New Zealand [PDF]

open access: yes, 2009
Apatite and zircon (U-Th)/He and fission track ages were obtained from ridge transects across the central Southern Alps, New Zealand. Interpretation of local profiles is difficult because relationships between ages and topography or local faults are ...

A probabilistic approach to the seismic hazard in Kashmir basin, NW Himalaya

open access: yesGeoscience Letters, 2019
Northwestern Himalaya is one of the most tectonically active domains of the Himalayan arc. The prevailing complex collisional tectonic setup is able to produce destructive earthquakes, most recent being the 8 October 2005 Kashmir earthquake (M7.6).
