云南堂上金矿床成因探讨
|
摘要
堂上金矿位于滇东南地区,研究显示矿床由同生热水作用形成矿源层或低品位矿床,有后期构造热液作用叠加富集,主成矿作用主要发生在燕山晚期。金矿床的形成经历了长期复杂的地质演化过程,大致可分为3个期次:矿源层形成期—构造热液叠加富集期8次生氧化富集期,具有多期次、多成因的特点。堂上金矿具有热水沉积,后期次热液改造叠加成矿的特点,矿床成因属热水沉积—构造热液叠加成因。
The Tangshang gold deposit is located in the southeastern Yunnan.The study result shows that the deposit formed by two stages of processes.The mineralization - source bed or low - grade layers was formed by the early syngenetic hot - water deposition, then super - imposited or enriched by the late -stage hydrothermal fluid.The gold mineralization mainly occurs in late Yanshanian period.The Tangshang gold deposit has gone through a long and complex geological evolutionary history,which can be divided into three phases:source bed formation stage,hydrothermal enrichment stage during structure activity,and oxidation enrichment stage. The Tangshang gold deposit has the characteristics of multiple ore - forming stages and multi - genesis,and belongs to the gold deposit of " thermal water sedimentation and hydrothermal fluid superposition and transformation along interstratified fracture zone".
