| 中文摘要: |
| 对滇西镇康芦子园矿床做了地表、地下工程编录及蚀变—岩相填图，在分析地质特征的基础上，选取II号矿带，依据六个中段的开拓工程对矿（化）体特征和矿化蚀变特征进行了系统研究。结果发现矿体倾向上及垂向上成矿元素具有Zn、Pb→Pb、Zn→Pb、Zn、Cu→Pb、Zn、Cu（Fe）→Fe、Cu（ Pb 、Zn）的分带规律，对应的矿化类型依次为大理岩型硫化铅锌矿→矽卡岩（绿泥片岩）型硫化铅锌矿→矽卡岩型黄铁黄铜矿→矽卡岩型磁铁矿，对应的蚀变带依次为碳酸盐—绿泥石化带→碳酸盐—石英—矽卡岩化带→矽卡岩化带→矽卡岩—黄铁矿化带→石榴子石矽卡岩化带。总结了矿化蚀变水平和垂向分带规律，并建立了矿床的矿化蚀变综合分带模式。 |
| 英文摘要: |
| This study is based on catalogs of ground and underground engineering and alteration- facies mapping in the Luziyuan, Zhenkang deposit of western Yunnan Province. It selected the ore zone II of this deposit as the target for analysis of geological features, and used data from six ore bodies in the middle of the pioneering work to reveal characteristics of mineralization and alteration. The results found zonation of ore-forming elements in both dipping and vertical directions, which is Zn, Pb → Pb, Zn → Pb, Zn, Cu → Pb, Zn, Cu (Fe) → Fe, Cu (Pb, Zn), and the corresponding types of mineralization include lead and zinc sulfide marble → skarn ( green clay schist ) lead-zinc sulfide skarn → pyrite chalcopyrite → skarn magnetite. The corresponding alteration zones are carbonate - chlorite zone → carbonate - quartz - skarn skarn zone → skarn zone - pyrite belt → garnet skarn zones. By summarizing horizontal and vertical zoning laws of mineralization and alteration, this work established a comprehensive zonation model for this deposit. |
