Thermochronology and landscape evolution
Physics Today, 2009Radioactive decay, the diffusion of daughter nuclides, and the annealing of fission tracks are being used to develop time-versus-temperature histories of rocks and the processes that sculpt Earth’s surface.

Alpha thermochronology of carbonates
Geochimica et Cosmochimica Acta, 2007Abstract Step-heating experiments on 17 calcites from 11 different samples and 6 dolomites from 5 samples suggest a closure temperature of He in carbonates ∼70 ± 10 °C for a cooling rate of 10 °C/m.y. The bulk closure temperature in some samples may tend slightly higher due to the presence of diffusion domains larger (and therefore more retentive ...

Apatite thermochronology in modern geology
Geological Society, London, Special Publications, 2009Abstract Fission-track and (U–Th–Sm)/He thermochronology on apatites are radiometric dating methods that refer to thermal histories of rocks within the temperature range of 40°–125 °C. Their introduction into geological research contributed to the development of new concepts to interpreting time-temperature constraints and substantially ...

Thermochronologic Approaches to Paleotopography
Reviews in Mineralogy and Geochemistry, 2007Although thermochronology cannot directly constrain paleoelevation, it can provide estimates of the form, location, and scale of paleotopographic relief, i.e., paleotopography, and its change through time. Unique thermochronologic perspectives on paleotopography come from 1) spatial patterns of surface and subsurface cooling ages or cooling histories ...

Fission‐track Thermochronology
Low-temperature thermochronology has become an essential tool when studying near-surface geological processes. Time-temperature constraints are vital to quantify and describe a large variety of geological processes, such as relief building, erosion and sedimentation or the maturation of organic matter in sedimentary basins.After a brief history ...openaire +3 more sources
Thermochronological Modeling with Artificial Intelligence
2023Thermochronology is a useful tool for constraining the timing and rates of tectonic uplift in mountain belts. Researchers rely on forward and inverse thermal models to constrain the many complex processes underlying thermochronologic datasets. Recent advancements in artificial intelligence (AI) sequence-to-sequence models make it possible to train a ...

Fundamentals of Fission-Track Thermochronology
Reviews in Mineralogy and Geochemistry, 2005Fission-track (FT) analysis has developed into one of the most useful techniques used throughout the geologic community to reconstruct the low-temperature thermal history of rocks over geological time. The FT method is based on the accumulation of narrow damage trails (i.e., fission tracks) in uranium-rich mineral grains (e.g., apatite, zircon ...

1999
Abstract In the previous chapter we reviewed both the conceptual and mathematical foundations of diffusion in solids and showed that the Arrhenius relationship could be linked with solutions of the diffusion equation (for a constant D) to yield an expression that relates temperature and heating duration to the degree of argon loss [eq ...

High-performance Computing in Thermochronological Modeling
Proceedings, 2014In the presented work high-performance parallel algorithms for thermochronological modeling of accretionary-collisional processes are considered. For numerical solution of the problem vector splitting schemes (in time) are combined with mixed FEM (in space).
