| 摘 要： | 云南个旧锡铜多金属矿集区为中国最重要的锡、铜多金属矿集区之一,经过同位素统计分析得出:硫的来源以生物地层沉积硫和海水硫酸盐为主,并可能混入了岩浆硫源;铅的来源复杂,并含有过量的放射性成因铅,明显有上地幔物质参与,且经过了均匀混合,组成稳定;碳来源由海相碳酸盐衍生而来,并主要与碳酸盐溶解作用有关,且可能有部分直接来源于深源碳;氧来源于浅部地壳经部分熔融形成.

| Abstract: | Yunnan Gejiu Tin-Copper polymetallic ore-concentrating district is one of the most important Tin-Copper polymetallic ore-concentrating districts.By the statistics and analysis of isotope,this paper concludes that:sulphur mainly comes from biostratigraphy deposition sulphur and seawater sulfates,probably mixed with the magma sulfur source;the source of lead is complicated and the lead contains an excessive amount of radiogenic lead,which is obviously involved with upper mantle materials.And they mix evenly a... |
