Types and Geological Characteristics of Gold Deposits in East Junggar, Xinjiang |
Located in northern Paleozoic terrigenous active belt of the Balkhash-Junggar microplate, East Junggar area experienced intense deformation and magmatism in the late Paleozoic, which was the main stage of gold me-tallization in geological history. There exist three gold types, i.e., gold deposits occurring in Neopaleozoic tuff, graywack and turbidite; gold deposits existing in Hercynian intermediate-acid rocks; and gold deposits existent in Neopaleozoic volcanic formation, represented by the Shuangquan gold deposit, the Huangyangshan gold deposit and the West Shuangfengshan gold deposit. These three gold types are different from each other in ore-bearing wall rock, deposit size, deposit grade, wall rock alteration, mineral assemblage and ore-forming element assem-blage, which are related to the deference in ore-controlling factors and metallogenic mechanism. |
