陕西潼关太峪金矿地质特征

Shaanxi province Tongguan County Taiyu geological characteristics of gold deposit

太峪金矿是陕西省潼关县较为典型的热液型金矿床,矿化富集与含金金属硫化物及石英脉密切相关。矿体产于岩体的接触带和构造带,产出部位明显受构造带的控制。矿体主要为大脉状、脉状、透镜状。矿床中发育典型的热液成因的矿物组合,矿石以强烈的绢云母化、碳酸盐化、绿泥石化、硅化及黄铁矿化为主要特征,矿石的金属矿物组合为自然金-银金矿-黄铁矿-方铅矿-闪锌矿-黄铜矿,矿化属中温热液成因。因此可推断,拾金坡金矿床属于与构造-岩浆活动有关的中温岩浆热液成因矿床。

Taiyu gold deposit is a hydrothermal type gold deposit in Tongguan County of Shaanxi province is a typical mineralization enrichment, and gold bearing quartz vein is closely related to metal sulfides and.The orebodies occur in the contact zone of rock and tectonic belt, control output part are obviously controlled by the tectonic belt. Ore bodies are large veins, vein, lenticular. Mineral assemblage of hydrothermal origin of typical development of the deposit, the ore by intense sericitization, carbonation, chloritization, silicification and pyritization as the main feature, metal mineral association as natural gold silver mine- pyrite and galena sphalerite chalcopyrite, mineralization belongs to mesothermal origin. So it can be inferred, Shijinpo gold deposit belongs to the medium temperature hydrothermal deposit related to tectonic magmatic activities.
