【摘要】 金厂沟矿田以金矿床为主 ,矿体与矿化点分布于燕山期中酸性杂岩体的内外接触带上。岩石化学及地球化学特征表明集安群变质岩系遭受中级变质 ,含有较高的金等金属成矿元素 ;中酸性杂岩体是地幔熔浆与壳源物质混杂形成 ;各成矿物质表现为幔源 ,同时汲取壳源 ,金来源于变质岩系和中酸性岩浆岩更多还原

【Abstract】 Deposits in the Jinchanggou ore field is mainly gold deposit, ore body and mineralized points are located in the inner and outer contact zone of intermediate acid complex rock body in Yanshan period. The character of geological and geochemical shows that the Jian Group metamorphic rocks with middling metamorphism, high grade gold and other metal elements. Intermediate acid complex rock body is formed by mixing of mantle magma and crustal material. The resource of mineralized materials is mantle and some crustal, gold is from metamorphic rocks and intemediate acid magmatic rock.更多还原
