| 中文摘要: |
| 通过贵州天柱重晶石矿整装勘查，在天柱云洞重晶石矿床下部发现铅锌矿体，矿体产于陡山沱组地层中，呈层状产出，规模较大，具有“上部重晶石矿，下部铅锌矿”的分布规律。从矿床地质、地化特征等方面研究，获得该矿床属于热水喷流沉积成因的初步证据。通过与典型SEDEX铅锌矿床对比，云洞地区铅锌矿的矿体形态、矿物组合、矿石组构、围岩蚀变，以及沉积、构造环境等，都与典型SEDEX铅锌矿床具有相似性。根据沉积、构造背景分析，认为湘西黔东具备热水喷流沉积（SEDEX）型铅锌矿床的成矿条件，预测天柱坪地—新晃—玉屏一带具有寻找大型铅锌矿床的前景。 |

| By barite fully equipped exploration in Tianzhu，the lead-zinc orebody was found in the lower Yundong barite deposit，it occur in the stratum of Doushantuo formation as layer，the scale is large，has the distribution feature of barite in the up side and lead-zinc in the down sideIn the deposit geology and geochemistry，the primary evidence that the genesis of deposit is hot water jet deposition was knownBy compare with the typical SEDEX lead-zinc deposit，the form，composition，assembly，wall rock alteration，sedimentary and structural environment of the lead-zinc deposit in Yundong area were similar to SEDEX lead-zinc depositAccording to the sedimentary and structural background，it’s thought west Hunan and east Guizhou had the metallogenic condition of hot water jet deposition type lead-zinc deposit，so it predicted Pingdi-Xinhuang-Yuping area of Tianzhu has big potential of lead-zinc deposit exploration. |
