摘要
从长坡-铜坑锡多金属矿矿床地质出发,分析其热水沉积成矿和岩浆热液成矿的证据,认为其主要成矿作用为泥盆纪热水沉积成矿,燕山期花岗岩浆热液则对早期的热水沉积矿体进行叠加改造,故矿床是热水沉积成矿-岩浆热液叠加改造的产物。
Starting from Changpo-Tongkeng Sn polymetallic deposit,this paper analyzes the evidences of sedi-mentation-exhalation mineralization and magmatic hydrothermal mineralization.It is believed that the prima-ry mineralization is Devonian sedimentation-exhalation mineralization.The Yanshanian granite magma hy-drothermal fluid superimposes the early sedimentation-exhalation ore-bodies,therefore,it is concluded that the deposit is sedimentation-exhalation genetic and magmatic hydrothermal fluid superimposed deposit.
