摘要
As one of the most classical deposits in Dian-Qian-Gui area, Car long gold deposit is the micrograined-disseminated deposits. The host rock is silicic sand-mudstone within Triassic Baifeng Formation. Country rock in roof is elastic rock of Middle-Upper Triassic and the rock in floor is carbonate rock of Carboniferous-Permian in core of Gaolong uplift. Gaolong uplift and the faults around uplift are the most important ore-controlling factors for gold orebody forming. Silication is closely related to the gold mineralization. By the analysis on the geological of ore deposit, geochemistry of element, isotope geochemistry, fluid inclusion and chronology in this paper, magma hydrothermal is proposed maybe the metallogenic hydrothermal and the power source for this gold forming. But Au element maybe comes from host rock of Triassic. Margin faults of Gaolong uplift act as the fluid-migrating conduits of ore-forming fluid. According on this research results, the metallogenic model is built on
