ABSTRACT The incision history of the Three Rivers (Salween, Mekong, and Yangtze) region in Southeast Tibetan Plateau has been linked to both tectonic climatic controls. In this study, we report new apatite (U‐Th)/He fission‐track thermochronology data from >6,000‐m‐high Kawagebo massif, which forms edge high plateau on western flank steepened knickzone reach middle Mekong River valley. Thermal‐history modeling a thermochronological age‐elevation profile shows rapid cooling since ~1.5 Ma...
Low-temperature thermochronology dates mineral cooling through the upper crust, enabling us to constrain rate and timing of landscape evolution over a range spatial-temporal scales (Reiners et al. 2005). However, constraining recent thermal histories timescales 105−106 years at temperature ranges between 25 75 oC remains challenge owing lack temporal resolution from existing thermochronometers. Deciphering time-temperature (
Many mountain glaciers have experienced an increase in supraglacial debris cover due to climate change. Understanding sediment transport processes glacier systems is important because the accumulation of affects evolution and response Tracking through glacial catchments difficult thus, pathway time scale englacially transported are relatively poorly understood. We quantify englacial within a using novel method combining luminescence rock surface burial dating ice-flow modelling (Margirier et...
The resurgence of Banded Iron Formations (BIFs) during the Neoproterozoic, following a billion-year hiatus, reflects significant geodynamic and climatic transition. Newly discovered Neoproterozoic BIFs in central Anti-Atlas region Morocco provide key insights into these processes. studied units are exposed within Bou Azzer-El Graara inlier (Central Anti-Atlas), an oceanic paleo-suture zone between Paleoproterozoic West African Craton remnants magmatic arc. This comprises 750 to 680 Ma arcs...
Constraining the timing of landslides is crucial for deciphering their triggering mechanisms. Recent years have seen a high number in tropical regions emphasizing need to explore links between climate and slope instability over longer timescales. While considerable data exists alpine, arctic, arid regions, limited preservation geomorphological features accounts lack environments (e.g., Pánek, 2019). The Rwenzori Mountains Uganda offer natural laboratory such study. upper part range...
Abstract Constraining the timescales of sediment transport by glacier systems is important for understanding processes controlling dynamics within glacierized catchments, and because accumulation supraglacial influences response to climate change. However, glacial can be difficult observe; transported englacially, subglacially, supraglacially or at ice margins, may stored temporarily on headwall slopes moraines before being (re‐)entrained ice. This study a proof concept use luminescence rock...

Abstract The Cordillera Blanca batholith (12–5 Myr) forms the highest Peruvian summits and builds footwall of normal fault (CBNF). Even if several models have been proposed, processes driving both exhumation extensional deformation along CBNF are still debated. Here we quantify emplacement depth northern Peru arc from late Miocene to present. Based on a compilation crystallization ages new thermobarometry data in batholith, propose that was emplaced at ~3 km successive sills 14 5 Ma. By...
Abstract The subduction of bathymetric highs, such as aseismic ridges, leads to far‐reaching changes in the dynamics zones with increased plate coupling and deformation upper plate.

  Constraining the pathways and time scales of englacial sediment transport is primary importance for both understanding processes that move through glacierised catchments quantifying response mountain glaciers to climate change. However, a more complex process than ice flow difficult observe; clasts can be transported englacially at margins, but also deposited into moraines before being re-entrained transport. We developed novel method taking Lagrangian approach combines...
Significant mass loss and increased rock debris cover have been observed across many mountain glaciers due to climate change. However, the dynamics of sediment transport through alpine are not fully understood should be investigated better constrain future evolution under a changing climate. Englacial is difficult observe that end, we quantify englacial time within glacier using novel method combining luminescence surface burial dating ice-flow modelling. Our study focuses on Mer de Glace,...
