Metallogenic Characteristics of Har Tolgoi Gold Polymetallic Deposit, Inner Mongolia

摘要

Har Tolgoi district, Inner Mongolia is located in the western part of northern margin of North China Platform, junction zone of North China Block and continental margin of North of Northern China. It belongs to Huogeqi minerogenic prospect, with favorable ore-forming geological condition. The stratum in researched area is mainly Agulugou Formation, Zhaertaishan Group, some rock mass such as Permian granodiorite can be seen, and N-E trend, N-W trend faults are preserved in this area. Through the research of geochemistry, geophysical anomaly and deposit geological characteristics, we deduce that Har Tolgoi gold polymetallic deposit is of magmatic hydrothermal type, which provides prospecting evidence of looking for the deposits of same type in this area.
