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 ...

Maturity of central Madagascar's landscape — Low-temperature thermochronological constraints

Gondwana Research, 2012
Abstract Low-temperature thermochronological data from two profiles across central Madagascar give apatite fission track and apatite (U–Th)/He ages ranging between 258 Ma and 176 Ma and from 239 Ma to 48 Ma, respectively. Thermal models derived from these data, as well as modelling of basement denudation and the sedimentary record, indicate that ...

The Application of Low-Temperature Thermochronology to the Geomorphology of Orogenic Systems

2018
The geomorphologic evolution of orogens has been a subject of revived interest and accelerated development over the past few decades, thanks to both the increasing availability of high-resolution data and computing power and the realisation that orogenic topography plays a central role in coupling deep-earth and surface processes.

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 ...

Onset of Carnegie Ridge subduction from low-temperature thermochronology

2021
<p>Cenozoic growth of the Andes has been strongly influenced by subduction dynamics, inherited crustal heterogeneities, and the superposed effects of climate. Subduction of the Carnegie Ridge in Ecuador has impacted late Cenozoic magmatism and tectonic activity, including the formation of a crustal sliver escaping northward.

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 ...

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

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 ...

High- to Low-Temperature Thermochronological Evolution of the Southeast Anatolian Orogenic Belt

19th International Petroleum and Natural Gas Congress and Exhibition of Turkey, 2013
The Southeast Anatolian Orogen was resulted from collision of the Arabian platform in the south and the Tauride platform in the north, following the Cretaceous to Miocene closure of the southern Neotethyan oceanic basin (Sengor and Yilmaz, 1981; Yilmaz, 1993; Yilmaz et al., 1993; Robertson et al., 2007a,b).

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.
