Low-temperature thermochronology: Resolving geotherm shapes or denudation histories?

Geology, 2006
Thermal histories derived from apatite fission-track data are remarkably consistent irrespective of tectonic setting and overall rate of cooling. Rapid cooling through the partial annealing zone is typically followed by slower cooling, and such histories can only be explained by systematic errors in the experimentally derived annealing rates used to ...

Application of Low-Temperature Thermochronology to Hydrocarbon Exploration

2018
The maturation of organic material into petroleum in a sedimentary basin is controlled by the maximum temperatures attained by the source rock and the thermal history of the basin. A cycle of continuous deposition into the basin (burial) and regional basin inversions represented by unconformities (unroofing) may complicate the simple thermal ...

Low‐temperature thermochronology of the Mt Painter Province, South Australia

Australian Journal of Earth Sciences, 2002
Apatite fission track results are reported for 26 outcrop samples from the Mt Painter Inlier, Mt Babbage Inlier and adjacent Neoproterozoic rocks of the northwestern Curnamona Craton of South Australia. Forward modelling of the data indicates that the province experienced variable regional cooling from temperatures >110°C during the Late Palaeozoic ...

Rock erodibility and the interpretation of low-temperature thermochronologic data

Earth and Planetary Science Letters, 2018
Abstract Rocks vary significantly in strength and erodibility. Here we evaluate if rock erodibility variations should be considered when interpreting thermochronologic datasets. We do this by applying 1D thermo–kinematic numerical models that exhume two lithologies of contrasting erodibility.

Low‐temperature thermochronological database of bedrock in the Japanese Islands

Island Arc, 2019
AbstractTo provide better access to thermochronological data and understand the long‐term denudation history of the Japanese Islands, we compiled a low‐temperature thermochronological dataset of fission‐track (FT) and (U–Th–Sm)/He (He) ages for apatite and zircon in bedrocks.

Low-temperature thermochronologic trends across the central Andes, 21°S–28°S

2015
In this paper, we merge more than 200 new apatite and zircon (U-Th)/He analyses and 21 apatite fission-track analyses from 71 new samples with previous published thermochronologic data using the same systems to understand the growth and large-scale kinematics of the central Andes between 21°S and 28°S.

Low-temperature thermochronology of the northern Rocky Mountains, western U.S.A.

American Journal of Science, 2012
We dated 86 borehole and surface samples from basement-cored Laramide uplifts of the northern Rocky Mountain foreland (Wind River, Beartooth, Bighorn and Laramie Ranges) using the apatite (U-Th)/He system, and eleven samples using the apatite fission-track system (Wind River and Bighorn Ranges). Apatite (U-Th)/He ages generally decrease with increasing

An Introduction to Low-temperature Thermochronologic Techniques, Methodology, and Applications

2013
Abstract Low-temperature thermochronometers can be used to measure the timing and the rate at which rocks cool. Generally, rocks cool as they move towards Earth’s surface by erosion or normal faulting (tectonic exhumation of the footwall), or warm as they are buried by sediments and/or thrust sheets, or when they are intruded by magma ...
