滇中易门县狮子山铜矿是产于扬子古陆边缘昆阳裂谷易门裂陷盆地内典型东川式层状矿床，是在昆阳裂谷背景下经同生沉积和二次富集作用而成，在鹅头厂组、落雪组、因民组等地层中均有不同矿体产出，矿床成因属热卤水沉积型东川式铜矿床。矿床的形成经历了同生阶段、成岩阶段和后生阶段。矿床在同生沉积阶段形成，成岩阶段固结成岩，后期的岩浆活动对矿床起到一定富集和改造作用。本文研究认为，矿床受地层与岩性、岩相古地理、构造、岩浆岩等因素的控制，通过对矿床成矿要素的分析和总结，归纳了该区的找矿标志，提出了矿区本部和近外围的找矿方向和靶区优选。

The Shizishan ore deposit in Yimen County of Central Yunnan Province is a typical Dongchuan type bedded ore deposit occurring in Yimen aulacogen of Kunyang rift within Proterozoic Yangtze Continent which was formed by syngenetic deposit and second enrichment under the Kunyang rift background, and its ore bodies occur in Etouchang Formation, Luoxue Formation and Yiming Formation, and genesis of deposit is hot brine sediment Dongchuan type ore deposit. The formation of ore deposit can be divided into simultaneously produce stage, diagenesis stage, and later produce stage. The Shizishan ore deposit formed in simultaneously produce stage, consolidated in diagenesis stage and late magmatic activity plays a certain role in enrichment effort and transformation effort. This paper considers that the ore deposit is controlled obviously by such factors as strata, lithology, lithofacies and paleogeographical environment, structure and magmatic activity, and belongs to hydrothermal fluid transformation type. The authors analyzed and summed up the metallogenic factors and put forward the prospecting criteria for Shizishan area. On such a basis, the prospecting directions in the Shizishan deposit and its adjacent areas are pointed out.
