Thermochronology of the modern Indus River bedload: New insight into the controls on the marine stratigraphic record [PDF]

open access: yes, 2004
The Indus River is the only major drainage in the western Himalaya and delivers a long geological record of continental erosion to the Arabian Sea, which may be deciphered and used to reconstruct orogenic growth if the modern bedload can be related to ...

Review of geothermochronological and thermobarometric techniques for the construction of cooling and exhumation curves or paths for intrusive igneous rocks

open access: yesBoletín Geológico, 2020
The present study reviews radiometric and thermobarometric techniques used to construct cooling curves or paths to characterize intrusive bodies and to calculate cooling and exhumation rates. To construct these curves or paths, the temperature, time and

From source to sink in central Gondwana: Exhumation of the Precambrian basement rocks of Tanzania and sediment accumulation in the adjacent Congo basin [PDF]

open access: yes, 2016
Apatite fission track (AFT) and (U-Th)/He (AHe) thermochronometry data are reported and used to unravel the exhumation history of crystalline basement rocks from the elevated (>1000 m above sea level) but low-relief Tanzanian Craton.

The Geochemical and Isotopic Record of Wilson Cycles in Northwestern South America: From the Iapetus to the Caribbean

open access: yesGeosciences, 2021
Isotopic and geochemical data delineate passive margin, rift and active margin cycles in northwestern South America since ~623 Ma, spanning from the Iapetus Wilson Cycle.

Cenozoic tectonics and geomorphic evolution of the lower Jinsha River on the southeastern margin of the Tibetan Plateau

open access: yesDizhi lixue xuebao, 2023
The southeastern margin of the Tibetan Plateau is distinguished by a vast transition zone with hundreds of thousands of square kilometers of low-relief surfaces, which provides an ideal window for unraveling the timing, process, and mechanisms of the ...

Tectonic denudation and topographic development in the Spanish Sierra Nevada [PDF]

open access: yes, 2007
The denudation history of the rapidly uplifting western part of the Spanish Sierra Nevada was assessed using apatite fission track (AFT) ages and 10Be analyses of bedrock and fluvial sediments.

Constraining the long-term evolution of the slip rate for a major extensional fault system in the central Aegean, Greece, using thermochronology [PDF]

open access: yes, 2006
The brittle/ductile transition is a major rheologic boundary in the crust yet little is known about how or if rates of tectonic processes are influenced by this boundary.

Middle–Late Cenozoic Stepwise Deformation Propagation in Eastern Tibet

open access: yesGeophysical Research Letters, 2023
The uplift and deformation styles of the Tibetan Plateau have been long debated on stepwise growth and crustal channel flow. Here, we offer new insight into this issue by constraining the pulsed exhumation history of the Yalong thrust belt in eastern ...

LA-ICP-MS APATITE FISSION-TRACK DATING OF THE SIBERIAN TRAPS INTRUSIONS: METHOD, FIRST RESULTS AND THEIR INTERPRETATION

open access: yesГеодинамика и тектонофизика, 2023
In this paper we present the results on apatite fission-track dating, which was first performed at the Schmidt Institute of Physics of the Earth, Russian Academy of Sciences, using the laser ablation inductively coupled plasma mass spectrometry (LA-ICP ...

Cenozoic Dynamic Topography of Madagascar

open access: yesGeochemistry, Geophysics, Geosystems, 2021
It has been proposed that Oligo‐Miocene regional uplift of Madagascar was generated and is maintained by mantle dynamical processes. Expressions of regional uplift include flat‐lying Upper Cretaceous‐Paleogene marine limestones that crop out at ...
