内蒙古乌拉盖地区火山作用与矿产

WuLagai areas of Inner Mongolia volcanism and minerals

研究区位于大兴安岭火山岩带中南部,中新生代火山作用强烈,不同的火山作用方式,伴随着不同的成矿作用,而昌图锡力锰铅锌银矿的形成可能与熔浆经分异、熔离或交代置换围岩中有用组分,贯入表层中的裂隙、断层或直接喷出火口有关。

The study area is located in the greater hinggan mountains South-central volcanic rock belt, the Cenozoic volcanism is strong, and different ways of volcanism, with different mineralization, and the formation of Changtuxili Mn- Ag-Pb-ZN silver force may be related to magma differentiation, liquation or replacement of displacement of surrounding rock of useful components, injection surface fissure, fault or directly in the overflowing crater.
