吉林三道溜河冰湖沟隐爆角砾岩型金矿床地质特征及找矿方向

Geological characteristics and prospecting of the cryptoexplosive breccia-type gold deposit of Binghugou,Sandaoliuhe,Jilin

三道溜河冰湖沟隐爆角砾岩型金矿床位于华北地台北缘东段太古宙高级变质区,出露岩石主要为变质深成岩。区内的隐爆角砾岩体展布受EW和NE向韧性剪切带控制。通过对冰湖沟隐爆角砾岩型金矿床的地质特征、矿化富集规律、控矿因素及地球化学、地球物理异常特征的研究表明,金矿体受隐爆角砾岩体和NE向韧性剪切带联合控制,成矿与中生代浅成低温热液关系密切,并指出了该区今后找矿方向。

Sandaoliuhe Binghugou cryptoexplosive breccia- type gold body is located in the Archean high- grade metamorphic zone on the eastern part of the northern margin of North China platform, mainly metamorphic plutonie rocks exposed. The cryptoexplos- ive breccia bodies are controlled by the EW and NE trending ductile shear zone. By the research of geological characteristics, minerali- zation accumulation, ore - controlling factors, geochemical and geophysical anomalies of Binghugou cryptoexplosive breccia - type gold deposit, the result shows that gold body is controlled by the cryptoexplosive breccia body together with NE trending ductile shear zone, and that its mineralization is closely related to Mesozoic epithermal, and that the prospecting of this area in future is proposed.
