| 摘 要： | 柳河县安口镇一带太古宙地体中发育有一条北东向韧—脆性剪切带,该带由糜棱岩化英云闪长岩、绿泥糜棱片岩、绢云千糜岩等组成,原岩为深成变质的长英质片麻岩。带内已知有金矿(点)6处,其成因是深成变质含矿流体沿剪切带上侵而形成的,受韧性剪切带控制的中低温热液型金矿,因此,加强对韧性剪切带的特征及控矿机制的综合研究对本区的进一步找矿工作将起到事半功倍的效果。

| Abstract: | There is a NE ductile-brittle shear zone in Archeozoic terrane in Ankou Town,Liuhe County,Jilin Province,which is composed of mylonitized tonalite,chlorite mylonite schist and sericitized phyllonite,the protolith is plutonic metamorphic felsic geniss.There are 6 known gold deposits(mineral occurrences) in the study area.From the genesis,it is formed by plutonic metamorphic ore-bearing fluid upintrude along the shear zone,belonging to low-to-moderate hydrothermal gold deposit controlled by the ductile shear zone.Therefore,the further comprehensive research on the characteristics of ductile shear zone and ore-controlling mechanism will get twice the result with half the effort for prospecting in the study area. |
