摘要
根据对拉拉铜矿床矿石中矿物共生组合及流体包裹体的研究,分析了成矿物理化学条件,认为矿床主要是在中温、中盐度、弱碱性和还原环境中沉淀富集的。根据同位素分析结果,结合地质特征,得出成矿物质来源于河口组地层、成矿作用以变质作用为主的结论。
According to the relations of associated minerals and analytical fluid inclusions the ore-forming physico-chemical conditions are studied. The authors believe that the ore-deposits were formedunder the conditions of medium temperature and salinty, weak alkalnity and silight reduction. Basedon the isotope compositions of the deposit it is suggested that the ore-forming elements came from He-kou Formation, the mineralization was of metamorphism.
