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 ...

Thermal history of the East European Platform margin in Poland based on apatite and zircon low-temperature thermochronology [PDF]

open access: yesSolid Earth, 2021
The Phanerozoic tectonothermal evolution of the SW slope of the East European Platform (EEP) in Poland is reconstructed by means of thermal maturity, low-temperature thermochronometry, and thermal modelling.

A revised alpha-ejection correction calculation for (U–Th) ∕ He thermochronology dates of broken apatite crystals [PDF]

open access: yesGeochronology, 2022
Accurate corrections for the effects of alpha ejection (the loss of daughter He near grain or crystal surfaces due to long alpha stopping distances) are central to (U-Th)/He thermochronometry.

Heated Topics in Thermochronology and Paths towards Resolution

open access: yesGeosciences, 2020
Thermochronometry is widely used to track exhumation, the motion of rock towards Earth’s surface, and to gain fresh insights into geodynamic and geomorphic processes.

Thermochronometry constraints on south West Greenland passive continental margin development

open access: yesCommunications Earth & Environment, 2023
Passive continental margins (PCMs) represent the interface between the marine and terrestrial realms. However, topographic evolution of PCMs is often difficult to decipher due to paucity of the preserved geological record. Here, we report uranium-thorium-

Tectonic evolution of the Gabal Loman area, North Eastern Desert, Egypt: implications from low-temperature multithermochronometry on the Arabian-Nubian shield

open access: yesFrontiers in Earth Science, 2023
The Neoproterozoic Arabian-Nubian Shield (ANS) in the Eastern Desert of Egypt encloses the regional thermal-tectonic history from its development till the Oligo-Miocene when the Red Sea rift system was initiated.

Long-wavelength late-Miocene thrusting in the north Alpine foreland: implications for late orogenic processes [PDF]

open access: yesSolid Earth, 2020
In this paper, we present new exhumation ages for the imbricated proximal molasse, i.e. Subalpine Molasse, of the northern Central Alps. Based on apatite (U-Th-Sm)/He thermochronometry, we constrain thrust-driven exhumation in the Subalpine Molasse ...

FTIR thermochronometry of natural diamonds: A closer look [PDF]

open access: yesLithos, 2016
Abstract Fourier Transform Infrared (FTIR) spectroscopy is a commonly-used technique for investigating diamonds, that gives the most useful information if spatially-resolved measurements are used. In this paper we discuss the best way to acquire and present FTIR data from diamonds, using examples from Murowa (Zimbabwe), Argyle (Australia) and Machado

Artificial intelligent identification of apatite fission tracks based on machine learning

open access: yesMachine Learning: Science and Technology, 2023
Over the past half century, apatite fission track (AFT) thermochronometry has been widely used in the studies of thermal histories of Earth’s uppermost crust.

Long-term erosion rates as a function of climate derived from the impact crater inventory [PDF]

open access: yesEarth Surface Dynamics, 2019
Worldwide erosion rates seem to have increased strongly since the beginning of the Quaternary, but there is still discussion about the role of glaciation as a potential driver and even whether the increase is real at all or an artifact due to losses in ...
