内蒙乌拉山金矿控矿条件及成矿作用

乌拉山金矿是华北地台北缘中西部地区近年来探明的有一定远景的金矿床。该矿床受大桦背岩体、韧性剪切带、脆性断裂构造和乌拉山群变质岩系等多种条件所控制，矿体呈脉状产出，成矿具有多期多阶段性，成矿时代较华北地台东缘金矿床早，为晚华力西期，其类型为中深成脉状金矿床

Study on the Gold Metallogeny and Ore Controlling Conditions in Wulashan Gold Deposit, Inner Mongolia

Wulashan gold deposit is one of the rather big deposits that have been discovered along the middle to west section of the north margin of north China platform in recent years. It is controlled by Dahuabei intrusive, E-W trending ductile shear zone, brittle fractures, and middle-high grade metamorphic rock series of Wulashan group, etc. Gold mineralization of this deposit is of the features of long history, complexity, and superimposition, being formed in late Hercynian and older than the deposits in the east section. Studying and summarizing its ore-controlling conditions and gold metallogeny not only have significance to ascertain gold metallogenic theory in the northwest part of north China platform but also have practical importance in guiding gold prognosis in the area.
