党河南山贾公台金矿位于祁连山加里东褶皱带,中祁连隆起和南祁连弧后盆地接触部位的南祁连区。金矿体赋存于中下奥陶统上岩组碎屑岩中,含矿岩性为构造角砾岩及碎裂黑云母斜长花岗岩。本文对成矿条件、控矿因素进行了归纳总结,并对中、低温热液蚀变碎裂岩型金矿床成矿模式进行了初步探讨。
The Party’s JGG gold deposit is located in the southern Qilian area at the contact part of the Qilian Mountains Caledonian Fold Belt, the Qilian Uplift and the South Qilian Back-arc Basin. The gold ore bodies occur in the Middle-Lower Ordovician Upper Cretaceous clastic rocks, and the ore-bearing lithology is tectonic breccia and fragmented biotite plagiogranite. This paper summarizes the metallogenic conditions and ore-controlling factors, and explores the metallogenic model of the medium- and low-temperature hydrothermal altered cataclasite-type gold deposits.
