Abstract上芒岗金矿由下部原生卡林型和上部 红色粘土型金矿体所组成,赋矿地层为侏罗系勐戛组砂泥质岩、白云质灰岩和二叠系沙子坡组泥硅质灰岩、白云岩。北东向上芒岗断裂构造与不整合面和岩溶的复合控制了矿床和矿体。围岩蚀变以硅化(似碧玉岩化)、黄铁矿化、碳酸盐化和粘土化为主,并具有水平与垂向分带性。地球化学研究表明,蚀变与矿化岩石的稀土含量与未蚀变泥质灰岩基本一致,成矿溶液为富CI^-型和富SO4^2-型,爆裂温度为183-378℃,δ^34S=6.471‰-21.965‰,δ^18O=9.3‰-11.6‰,δD=-70‰--77‰,^206Pb/^204Pb=19.551-20.05,^207Pb/^204Pb=15.690-16.240,^208Pb/^204Pb=38.710=40.137。红色粘土型矿石的红土化作用只达到粘土阶段。
