| 摘 要： | 天宝山铅锌矿是我国川滇黔低温成矿域内大型铅锌矿床之一.矿床主要由天宝山和新山2个矿段组成,矿床主要矿石矿物为闪锌矿、方铅矿及少量黄铁矿、黄铜矿.在野外观测的基础上,对采集的岩矿石标本及对应的光片进行了系统的鉴定和研究.根据矿物组合特征和矿物相互之间的穿插关系,确定了它们形成的先后顺序,进而划分出3个成矿期和5个成矿阶段.

| Abstract: | The Tianbaoshan deposit, composed of two ore blocks, i.e. Tianbaoshan and Xinshan, is one of the largest PbZn deposits in the Yunnan-Guizhou-Sichuan epithermal metallogenic province. The ore minerals are mainly sphalerite and galena, with minor pyrite and chalcopyrite. Based on field observation, the authors identify and study the rock and mineral samples and polished sections. According to the assemblage and interrelations of minerals, the forming sequence is determined. The Tianbaoshan Pb-Zn deposit is then divided into 3 metallogenic periods with 5 mineralization stages. |
