| 摘 要： | 西藏洞中拉铅锌矿床位于冈底斯成矿带东段北亚段,矿体发育于上石炭统—下二叠统来菇组灰岩—大理岩化灰岩内的矽卡岩中。在分析该矿床成矿地质背景及对矿区控矿构造分析的基础上,对比前人数据较为系统的研究了矿石S、Pb同位素组成,探讨了成矿物质的来源。表明矿区矿石硫同位素分布范围较窄,呈塔式分布,总硫同位素值约为5.21‰,具有岩...

| Abstract: | Dongzhongla lead-zinc deposit in Tibet is located in the north sub-zone of eastern section of Gangdise metallogenic belt.The ore body mainly occurs as stratoid form in the skarn and skarnization marble of the Middle Carboniferous-Upper Permian Laigu Formation.Based on analysis of the ore-forming geological backgrounds and structure of ore,the paper studied systematically the composition characteristics of S and Pb isotopes in the ore,and discussed the sources of the ore-forming materials.The studies show th... |
