Substantial spatial variation in glacial erosion rates in the Dronning Maud Land Mountains, East Antarctica

open access: yesCommunications Earth & Environment, 2021
The topography of the Dronning Maud Land Mountains, Antarctica, has become more pronounced and rugged since preglacial times due to higher glacial erosion at low elevations and lower erosion at high elevations, according to low-temperature ...

Northward Growth of the West Kunlun Mountains: Insight From the Age–Elevation Relationship of New Apatite Fission Track Data

open access: yesFrontiers in Earth Science, 2021
The Cenozoic collision between India and Asia promoted the widespread uplift of the Tibetan Plateau, with significant deformation documented in the Pamir Plateau and West Kunlun Mountains.

New fission-track results from the northern Chiapas Massif area, SE Mexico: trying to reconstruct its complex thermo-tectonic history

open access: yesRevista Mexicana de Ciencias Geológicas, 2018
The Chiapas Massif Complex, which represents the crystalline basement of the southern Maya block within the North American plate, records numerous thermo-tectonic and magmatic events that occurred in southern Mexico at least since the late ...

Resurgence initiation and subsolidus eruption of cold carapace of warm magma at Toba Caldera, Sumatra

open access: yesCommunications Earth & Environment, 2021
Post-caldera eruptions at Toba Caldera, Sumatra, following the supereruption 74,000 years ago, sampled cooler margins of the warm magma reservoir and imply its heterogeneity, according to thermochronology analyses coupled with Bayesian statistics.

Miocene orographic uplift forces rapid hydrological change in the southern central Andes [PDF]

open access: yes, 2016
Rainfall in the central Andes associated with the South American Monsoon and the South American Low-Level Jet results from orographic effects on atmospheric circulation exerted by the Andean Plateau and the Eastern Cordillera.

Volcanic History of Rodrigues Island and Its Relationship With the Central Indian Ridge and the Réunion Hotspot

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 4, April 2026.
Abstract Many intraplate volcanic chains are explained as hotspot trails formed by plate motion over mantle plumes, yet some deviate from this model. The Rodrigues Ridge, a volcanic lineament extending eastward from the Réunion hotspot track toward the Central Indian Ridge (CIR), is one such case.

Tectono-Thermal Evolution of the Red Sea Rift

open access: yesFrontiers in Earth Science, 2021
The Oligocene-Recent Red Sea rift is one of the preeminent examples of lithospheric rupture in the recent geological past, forming the basis for many models of how continental breakup occurs and progresses to the formation of new oceanic crust ...

Thermal structure and exhumation history of the Lesser Himalaya in central Nepal [PDF]

open access: yes, 2004
The Lesser Himalaya (LH) consists of metasedimentary rocks that have been scrapped off from the underthrusting Indian crust and accreted to the mountain range over the last ~20 Myr. It now forms a significant fraction of the Himalayan collisional orogen.

Cryogenian Glacial Erosion and Tectonics as Agents of Crustal Recycling

open access: yesTerra Nova, Volume 38, Issue 2, Page 87-96, April 2026.
ABSTRACT Zircon preserves evidence of recycling processes that link surface environments to the mantle. Combined δ18O‐εHf in zircon fingerprints magmatic sources and tracks how crustal material is reworked over time. We apply statistical analyses to a global compilation that apparently resolves shifts in zircon U–Pb, δ18O, and Lu‐Hf data spanning the ...

The state of the art of Low-temperature Thermochronology in Brazil

open access: yesJournal of the Geological Survey of Brazil, 2020
Low-temperature thermochronology focuses on the comprehension of the upper crust’s thermal history, where morphotectonic processes take place. We present a robust compilation (1120 data in almost 30 years of research) of fission-track and (U-Th)/He ...
