Late Jurassic Intracontinental Extension and Related Mineralisation in Southwestern Fujian Province of SE China: Insights from Deformation and Syn-Tectonic Granites

Mantle-Derived Noble Gas Isotopes in the Ore-Forming Fluid of Xingluokeng W-Mo Deposit, Fujian Province

“…The WYMB is located in the northeast of the Cathaysian block and distributed in the NNE direction (Figure 1), bounded on the north by the Shaoxing-Jiangshan-Pingxiang fault and adjacent to the Qinhang metallogenic belt on the southeast edge of the Yangtze block, on the west by the Yingtan-Anyuan fault, near the NLMB, and on the east by the Lishui-Zhenghe-Dapu fault to the southeast coastal metallogenic belt [46,47]. The WYMB has experienced major geological events such as the formation and cracking of the Cathaysian block, the collision and splicing of the Cathaysian block and the Yangtze block, the collision between the north China block and south China block, and the subduction of the Pacific plate to the Eurasian continental margin, among which the Yanshanian tectonic magmatic activity is the strongest [48,49], and forming a large number of Cu, Au, Ag, Pb, and Zn deposits [50][51][52][53], such as the Zijinshan Cu-Au deposit and the Lengshuikeng Ag-Pb-Zn deposit, as well as some large W deposits, such as the Shangfang W deposit and Xingluokeng W-Mo deposit. The strata in WYMB include the upper Archean to Quaternary, in which the pre-Devonian is the basement rock series, the Devonian Middle Triassic is the caprock rock series dominated by marine sedimentation, and the Meso Cenozoic is the continental clastic and volcanic rock series.…”
