Study on multi-period palaeotectonic stress fields simulation and fractures distribution prediction in Lannigou gold mine, Guizhou [PDF]

, 2023
A significant controlling factor for gold mineralisation is the tectonic stress field, and the fractures formed under its action are the migration channels and ore-holding spaces of ore-forming fluids, which often directly control the migration and ...

Geochronology, genesis and landscape of Yanshanian granite in Guangzhou area, central Guangdong Province of China [PDF]

SN Applied Sciences, 2019
Based on field geological investigation and zircon U–Pb isotope dating of granites in Guangzhou, central Guangdong, the formation age, petrogenesis and weathering characteristics of granites are discussed. The LA-ICPMS zircon U–Pb ages of Huolushan and Liuqianshan granites in central Guangdong are 159.1 ± 3.5 Ma and 156.2 ± 4.4 Ma, respectively.

Simulation of tectonic stress field and prediction of tectonic fracture distribution in Longmaxi Formation in Lintanchang area of eastern Sichuan Basin

Frontiers in Earth Science, 2022
Shale is a low-porosity and low-permeability reservoir, and structural fractures are the main controlling factor for the migration and accumulation of shale gas. Moreover, tectonic fractures are controlled by the paleo-tectonic stress field.

Brittle Structural Control and Fluid Progress of the Jinqingding Gold Deposit: Implications for Epizonal Gold Mineralization

Acta Geologica Sinica - English Edition, EarlyView.
ABSTRACT The Jinqingding gold deposit in eastern Jiaodong is a significant gold mineralization within the Muping–Rushan metallogenic belt. This study integrates structural analysis and trace element geochemistry of sulphides to elucidate ore‐controlling mechanisms and metallogenic models.
