摘要
易门狮山铜矿床产于元古界昆阳群绿汁江组狮山段泥质、炭质白云岩及粉砂岩中。狮山段由黑色层（Ｍｃ）、过渡层（Ｍｇ）和紫色层（Ｍｐ）组成。在矿床地质特征研究基础上，总结了该矿床的微观规律及其特征（包括化学组分、微量元素在狮山段、矿体中的分配；元素共生组合及演化规律；有机碳的含量与成矿；硫同位素及硫源；矿物包裹体特征等）。提出成矿元素经历了离散、合并、分解和矿体形成的演化过程。
The Shishan Cu deposit of Yimen is formed in the muddy carbonaceous dolomitite and siltstone of Shishan Member, Luzhijiang Formation, Proterozoic Kunyang Group. The Shishan Member is composed of black layer(Mc), transitional layer(Mg) and purple layer(Mp). Based on the study of geolodical characteristics of the deposit, this paper sums up the microscopic law and characteristics of it, including the distribution of chemical constituents,trace elements in Shishan Member and ore bodies; the element paragenesis and evolution law; the content of organic C and metallogenesis; the S isotope and S source and the inclusion characteristics of minerals, and put forward that the metallogenetic elements have undergone the evolution of dispersion, combination, decombination and ore body formation.
