AusGeochem and Big Data Analytics in Low-Temperature Thermochronology
2021<p>The AuScope Geochemistry Network (AGN) and partners Lithodat Pty Ltd are developing AusGeochem, a novel cloud-based platform for Australian-produced geochemistry data from around the globe. The open platform will allow laboratories to upload, archive, disseminate and publish their datasets, as well as perform statistical analyses and ...

Low-temperature thermochronology applied to ancient settings
Journal of Geodynamics, 2016Abstract Low-temperature thermochronometric dating techniques are commonly used to reveal and quantify the spatial and temporal pattern of cooling and exhumation in many active mountain belts. These methods illuminate the relationship between rock exhumation, and the processes that bring rock to the surface, including climate-driven surface processes.

Diachronous exhumation of the Carpathians from low-temperature thermochronology
2021<p>The Carpathians fold-and-thrust belt results from oblique collision of ALCAPA and Tisza-Dacia plates with the eastern European margin. It formed during the Oligocene and Miocene, propagating laterally from NW to SE as clearly demonstrated by balanced-cross sections (Nakapelyukh et al., 2017; Castellucio et al., 2016; Merten et al ...

Using thermoluminescence signals from feldspars for low-temperature thermochronology [PDF]
Quaternary Geochronology, 2017 Natural thermoluminescence (TL) signals from feldspar crystals extracted from thermally stable drill cores (View the MathML sourceC) exhibit a strong dependence on geologic and laboratory thermal conditions. As burial temperature increases, the position of the TL glow curve at half-maximum intensity (i.e., the T1/2 parameter) shifts to higher ...

Rock erodibility and the interpretation of low-temperature thermochronologic data
Earth and Planetary Science Letters, 2018Abstract 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 thermochronology of fault zones
2020<p>Thermal signatures as well as timing of fault motions can be constrained by thermochronological analyses of fault-zone rocks (e.g., Tagami, 2012, 2019).&#160; Fault-zone materials suitable for such analyses are produced by tectocic and geochemical processes, such as (1) mechanical fragmentation of host rocks, grain ...

Reconstruction of palaeotopography from low-temperature thermochronological data
Geological Society, London, Special Publications, 2009Abstract Thermochronology can provide information on palaeotopography and its evolution. We present a new method to reconstruct the shape of the palaeotopography from the palaeoisotherm derived from low-temperature thermochronological data.

Application of Low-Temperature Thermochronology to Craton Evolution
2018The view that cratons are tectonically and geomorphologically inert continental fragments is at odds with a growing body of evidence partly based on low-temperature thermochronology (LTT) studies. These suggest that large areas of cratons may have undergone discrete episodes of regional-scale Neoproterozoic and/or Phanerozoic heating, and cooling from ...

Low‐temperature thermochronological database of bedrock in the Japanese Islands
Island Arc, 2019AbstractTo 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.
