A Late Paleozoic Hydrothermal Gold Mineralization Event in the Northern Margin of the North China Craton: Evidence of In Situ Apatite U‐Pb Dating and Hg Isotope Tracing of the Giant Hadamengou Gold Deposit

open access: yesGeochemistry, Geophysics, Geosystems, Volume 26, Issue 5, May 2025.
Abstract The northern margin of the North China Craton (NCC) hosts large numbers of hydrothermal gold deposits, with mineralization ages ranging from the Paleozoic to Mesozoic eras. The genesis of these deposits has been primarily ascribed to magmatic‐hydrothermal or crustal‐metamorphic fluid models. The Hadamengou gold deposit (>170 t Au), the largest

Ten Questions of East Asian Tectonics

open access: yesActa 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 ...

Cretaceous fractionated I-type granitoids and metaluminous A-type granites in SE China: the Late Yanshanian post-orogenic magmatism

open access: yes, 2000
The Late Yanshanian Orogeny (130-90 Ma) encompasses an important Mesozoic magmatic event in the crustal evolution of SE China. Products of post-orogenic magmatism, widely distributed in the eastern part of Zhejiang and Fujian provinces known as the ...

Formation and geodynamic implication of the Early Yanshanian granites associated with W–Sn mineralization in the Nanling range, South China: an overview

open access: yes, 2018
The Nanling range (Nanling) is characterized by intense and widespread Mesozoic magmatism related large-scale W–Sn mineralization. A summary of geochemistry, geochronology, and petrogenesis for the W–Sn-bearing granites has been carried out in this study.

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

open access: yesGeochemistry, 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.
