Discriminating Tectonic Setting of Igneous Rocks Using Biotite Major Element chemistry−A Machine Learning Approach

Geochemistry, Geophysics, Geosystems, 2021
The composition of igneous biotite is a potential indicator of the geologic environment of its host rock. Here, we apply two machine learning models−eXtreemly Greedy tree Boosting (XGBoost) and light gradient boosting machine (LightGBM) to classify ...

Resolving the Tectonic Setting of South China in the Late Paleozoic

Geophysical Research Letters, 2022
The tectonic setting of South China during the late Paleozoic is essential to understanding the geodynamics off the eastern margin of Pangea supercontinent due to its unique paleo‐position at the confluence of the Paleo‐Tethys and Panthalassic oceans ...

Seismic anisotropy of the upper mantle beneath Thailand: Tectonic setting constrained by shear-wave splitting analysis [PDF]

Songklanakarin Journal of Science and Technology (SJST), 2020
The tectonic setting of the lithosphere and upper mantle underneath Thailand varies and changes substantially over short distances. We have mapped these variations using shear wave splitting (SWS) analysis.

Sedimentology and compositional characteristics of siliciclastic and associated sediments in Ruvu basin: implication on paleo-depositional environment, provenance, and tectonic setting

Geology, Ecology, and Landscapes, 2022
The paleo-depositional environment of the Ruvu basin ranges from alluvial, floodplain, low- and high-energy fluvial channels, and deltaic sub-environments of Ngerengere beds, Tanga beds, and Jurassic Msata formations.
