摘要
从成矿地质背景、矿床地质特征及地质发展史出发,依据矿石光片鉴定及鲕状黄铁矿电子探针分析,综合分析前人提出的岩浆热液成矿和热水沉积成矿的证据,认为个旧锡多金属矿床既存在热水沉积成矿作用,又有岩浆热液成矿作用,为热水沉积-岩浆热液叠生矿床。
This paper is based on the geological background, the main type of tin deposit and the geological history of southeastern Yunnan. Furthermore, according to the analysis of the genesis of magmatic hydrothermal deposits and hydrothermal deposits, it is thought that the Gejiu tin deposit is the result of both hydrothermal sedimentary mineralization and magmatic hydrothermal mineralization, i.e., a hydrothermal sedimentarymagmatic hydrothermal mineralization superposed ore deposit.
