摘　　要：武当地块地质构造复杂,岩浆活动频繁,发育大量基性超基性岩体,是寻找银、金、铂、钯、铜、铁等多金属矿产的有利地区。从银洞山岩体的岩石学、岩石化学特征等方面,探讨了银洞山岩体就位机制,初步认为银洞山岩体属幔源玄武岩浆分异产物。Wudang block is complex in geological structure, with frequent magmatic activities and large amount of basic and ultrabasic massifs, so it is a favorable area for exploring metallic deposits such as silver, gold, platinum,palladium and copper and iron. Based on the petrologic and petrochemical characters of Yindongshan massif, this paper discussed the location mechanism of Yindongshan massif and considers it as the differentiate of mantle - derived basaltic magma.
