| 摘 要： | 西林河脆-韧性剪切带是区域上富尔河-古洞河岩石圈深断裂带的重要组成部分,总体走向330°,由东部(F1,F2,F3)、中部(F4,F5)和西部(F6)3条脆-韧性剪切断层带组成。东部带以脆性变形为主,延长约4km;中部带除脆性变形外兼有塑性变形,延长约5km;西部带以塑性变形为主,总延长5.5km。构造岩比较发育,分为脆性变形构造岩系列和塑性变形构造岩系列。构造岩的变形和退变作用同时进行。西林河脆-韧性剪切带反映了西林河金矿的成矿时代为燕山期,是金成矿的导矿和容矿构造。本着就矿找矿的原则,根据成矿地质条件,在已有的6个矿体的延伸方向进行追索找矿;根据边缘成矿作用观点,可在矿区内太古宙灰色片麻岩与元古宙浅变质岩的接触带进行找矿。确立了6条找矿标志。

| Abstract: | Xilinhe brittle-ductile shear zone is a important part of Fuerhe-Gudonghe lithospheric deep fault and consisted of three brittle-ductile shear faults(F 1,F 2,F 3 in the east;F 4,F 5 in the central;F 6 in the west) In the east belt,the brittle deformation,about 4 km long,is the major structure; in the central belt,are the brittle and plastic deformations,about 5km;in the west belt,is the plastic deformation,about 5 5km Tectonite developed well and can be classified into two series of brittle deformations and plastic deformation The deformation and retreated metamorphism developed simultaneously The metallogenic age of Xilinhe gold ore was Yanshanian period Xilinhe brittle-ductile shear zone is the conducting and host structures of gold ore Based on the geological condition for mineralization of prospected deposit,we should make a follow-up prospecting in the extending direction of the six orebodies According to the view of marginal mineralization,the exploration can be carried out in the contact zone of Archean grey gneiss and Proterozoic light metamorphic rock,and five prospecting criteria have been determined |
