浅谈栾川县白庙沟钼矿地质特征及成矿规律

Deposit geological characteristics and metallogenic regularity of Baimiao ditch in Luanchuan County

栾川县白庙沟钼矿区位于华北板块的一个褶皱山系断裂层上,所以该地区的地质运动较为活跃,区域内的岩浆活动十分强烈。栾川县白庙沟钼矿区有少量的元古界熊耳群火山层,岩石接触带控制着整个矿体的空间位置,断裂构造对成矿富集作用影响十分明显,钼矿主要集中在黑云母花岗岩与熊耳群岩层上部或顶部附近。成矿热液主要来源于整个岩体,在多次构造活动中,岩体逐渐的形成了次级构造断裂,发生破碎及蚀变,这也是成矿的必要条件。

A fold mountains fracture layer of white Miao Gou molybdenum mine in Luanchuan county is located in the North China plate,so the geological movement in the area is relatively active,regional magmatic activity is very strong.Bai Miao Gou County of Luanchuan molybdenum mine are Proterozoic Xiong＇er Group volcano layer small,space rock contact zone of the ore body,the fracture structure is a very obvious effect on mineralization enrichment,molybdenum ore is mainly concentrated in the vicinity of biotite granite and rock top or upper part of the Xiong＇er group.The ore-forming hydrothermal solution mainly comes from the whole rock mass.In the multiple tectonic activities,the secondary structure fracture is formed gradually,and the fracture and alteration are formed.
