Ten Questions of East Asian Tectonics

Acta Geologica Sinica - English Edition, Volume 99, Issue 2, Page 297-319, April 2025.
Abstract East Asian continental tectonics challenges the plate tectonics paradigm with its diffuse intraplate deformation, magmatism, and earthquakes. Despite extensive studies, fundamental questions persist. This review examines ten critical questions of East Asian tectonics, including the thickness of the continental lithosphere, the origin of the ...

Triassic Tectonic Affinity to Indochina‐East Malaya Block for West Sumatra and Paleo‐Tethys Implications: Constraints From Late Triassic Igneous Rocks

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 3, March 2025.
Abstract Mesozoic igneous rocks from Sumatra provide crucial insights into the temporal‐spatial connection with the Eastern Tethys Domain. This study presents new zircon ages and whole‐rock elemental data for the Late Triassic igneous rocks in West Sumatra. These igneous rocks yield consistent ages of 227–211 Ma.

Geological Knowledge‐Guided Dual‐Branch Deep Learning Model for Identification of Geochemical Anomalies Related to Mineralization

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 1, March 2025.
Abstract Geochemical survey data are a type of spatial big data that play an increasingly significant role in mineral exploration. One challenge in the era of big data is how to mine geochemical data in support of mineral exploration. In this study, based on a generative adversarial network framework, we proposed an unsupervised spatial–spectrum dual ...
