| Metallogenic Factors and Prospecting Directions in the Shizishan Copper Deposit and Its Adjacent Areas in Yimei County of Central Yunnan Province |
| 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. |
