| 中文摘要: |
| 云南省镇康芦子园铅锌矿为近年来发现的的超大型多金属矿床，矿体主要赋存于上寒武统沙河厂组中，受NE向断裂及其旁侧伴生构造所控制，空间上具有等间距侧伏分布的特征。围岩蚀变发育，矿化经历了中低温和中高温两个阶段，大理岩化、夕卡岩化、黄铁矿化、硅化及其蚀变叠加部位矿化强烈。成矿物质主要来源于含矿地层及深部隐伏岩体，通过对矿区含矿地层岩性、控矿断裂构造、围岩蚀变及矿石组构等地质特征的研究，认为该矿床的形成与多期（次）构造运动、岩浆热液活动有关，是一个具有多期次和多种矿质来源的热液夕卡岩型铅锌铁多金属矿床。 |
| 英文摘要: |
| Luziyuan Pb-Zn deposit in, Zhenkang Town, Yunnan Province is asuper-large polymetallic deposit discovered in recent years. The ore body mainly occurs in Upper Cambrian Shahechang formation and is controlled by NE faults and the associated sub-structures. Spatially, the ore bodies are plunged and distributed in equal distance. Wall-rock alterations are developed. Mineralization is dived into meso-epithermal stage and mesothermal-high temperature stage. Where marblization, skarnization, pyritization, silicification are developed and overprinted mineralization is strong. Ore materials are mainly derived from the ore-bearing strata and the deeply seated intrusive body. Based on study on lithologies of ore-bearing strata, the ore-control fracture, wall rock alteration and the ore fabric, the deposit is related to multi-staged tectonic movement and magmatic hydrothermal fluid and is a hydrothermal-skarn type Pb-Zn-Fe polymetallic deposit. |
