Batholith recorded mesozoic multistage tectonic evolution of the South china block: A case study of the guandimiao intrusions

open access: yesFrontiers in Earth Science, 2022
South China is a well-known grand felsic igneous rocks province. However, it is still controversial and not well understood whether the Mesozoic tectono-magmatic pattern is dominated by the subduction of the paleo-Pacific oceanic plate. In this study, we

Structural style and kinematics of the Taihang-Luliangshan fold belt, North China: Implications for the Yanshanian orogeny [PDF]

open access: yesLithosphere, 2019
AbstractThe Middle–Late Jurassic to earliest Cretaceous fold belts of the Yanshanian orogen in North China remain enigmatic with respect to their coeval deformation histories and possible relationship to the contemporaneous Cordilleran-style margin of eastern Asia.

CNXT‐Ti‐LT–Based Multi‐Scale Feature–Aware Susceptibility Mapping of Rainfall‐Induced Clustered Landslides in Southeast China

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 2, April 2026.
Abstract This study focuses on the clustered landslide event triggered by intense rainfall on 16 June 2024 in the Fujian–Guangdong–Jiangxi border region, aiming to develop an efficient deep learning model for high‐accuracy landslide susceptibility mapping. Based on the mapped landslide distribution and insights from field investigations, we constructed

LA-ICP-MS Zircon U-Pb Dating of Alkali-Feldspar Granites from the Dawan Mo-Be Deposit, Xiapu, Fujian Province

open access: yesYankuang ceshi, 2018
BACKGROUND The Mo-Be deposit in Xiapu Dawan, Fujian Province is located in a volcanic rock area. Mineralization may be closely related to magmatic activity and fracture structure.

Mineralization Characteristics of the Li‐rich Muscovite Granite in the Mufushan Batholith, Central China: Insights into the Rare Metal Mineralization Models of Batholithic Complex

open access: yesActa Geologica Sinica - English Edition, Volume 100, Issue 1, Page 137-155, February 2026.
Abstract Elucidating the mineralization mechanisms of individual granitic stages and tracing magmatic evolution processes are critical for establishing mineralization models of large‐scale batholiths. The Mufushan granitoid batholith, renowned for multistage magmatism and large‐scale rare metal mineralization, mainly comprises biotite, two‐mica, and ...

Identifying Framboidal Pyrrhotite: A Proxy for Hydrothermal Alteration of Organic‐Rich Sediments

open access: yesGeophysical Research Letters, Volume 52, Issue 23, 16 December 2025.
Abstract Framboidal pyrrhotite, in sharp contrast to framboidal pyrite, has been rarely reported, and its formation remains poorly understood. Here we report its clear identification in a shale‐gas well core and explore its potential as a proxy for diagenesis or low‐grade metamorphism of organic‐rich sediments.

Formation process and controlling factors of tight buried-basement hill reservoirs:a case study of Weixinan Depression, Northern Beibu Gulf Basin, South China

open access: yesFrontiers in Earth Science
In relatively stable sedimentary basins, the formation of buried-basement hill reservoirs mainly occurs after the basin basement forms and before the overlying sedimentary cover layer is filled. Represented by the Beibu Gulf Basin in the South China Sea,

Evaluation of Present Tectonic Stress Field and Permeability of Coalbed Methane Reservoirs by Inversion of Logging Data From Longtan Formation, Dahebian Block

open access: yesEnergy Science &Engineering, Volume 13, Issue 11, Page 5198-5217, November 2025.
ABSTRACT The permeability of coal reservoirs is predominantly controlled by the present tectonic stress field. This study systematically integrates macro‐ and micro‐scale analytical methods to investigate the controlling mechanisms of tectonic stress on pore‐fracture characteristics and permeability in the Longtan Formation coal reservoirs.
