河南槐树坪矿区缓倾斜金矿体特征及找矿方向
|
摘要
槐树坪金矿是近年来在熊耳山地区发现的由缓倾斜断裂控矿的大型蚀变岩型金矿,主矿体赋存于中元古界熊耳群鸡蛋坪组的层间滑脱缓倾斜断裂中,深入研究缓倾斜金矿体特征对确定该区下一步找矿方向,以及在熊耳山地区寻找同类型金矿床具有重要的指导意义。结合野外地质调查和室内研究,对槐树坪缓倾斜金矿体特征及岩石地球化学特征进行了深入研究,结果表明:缓倾斜矿体在剖面上呈舒缓波状的薄脉形态,沿走向、倾向相对稳定;矿体厚度、品位变化较稳定,矿化蚀变以黄铁矿化、硅化和钾化为主;Au元素与Bi、Ag元素显著相关,金矿体原生晕轴向分带特征明显,前缘晕与尾晕元素叠加共存,呈现出"反分带"现象,说明矿体向深部仍有一定的延伸。缓倾斜层间滑脱断裂是槐树坪矿区最重要的含矿容矿构造,控制着金矿体的产出形态、产状及矿化富集区,综合分析认为沿缓倾斜矿体走向及倾向是找矿的主要方向。
Huaishuping gold mine,found in the area of Xiong'er mountain for the past few years,is a large metamorphic rock type gold deposit,which is controlled by the slightly dipping faults.The main orebody is located in the slightly dipping decollement fracture structure between the layers of Jidanping Formation in Mesoproterozoic Xiong'er Group.It has certain guiding significance for determining the next step prospecting direction and looking for the same type of gold deposits by researching on slightly dipping orebody characteristics in the area of Xiong'er mountain.The slightly dipping orebody showed wavelike thin vein of form,and relatively stable along the strike and dip in profiles.The alteration have pyritization,silication and potassium.Orebodies are stable in thickness and grade.The element of Au was significantly correlated with Bi and Ag elements,the axial zoning of primary halo of gold deposits was obviously,and the leading edge halo and tail halo elements overlap and coexist,which was"reverse banding"phenomenon.The orebodies are also extend to deep.The interlayer slip gentle-dipping faults are the most important ore-bearing structures in this area,which controls the morphology,occurrence and mineralization of gold deposits.This thesis point out that along the strike and tendency of the slightly dipping orebody is the main direction of prospecting.
