| 摘 要： | 宁南跑马铅锌矿集中产于下寒武统麦地坪段潮坪-泻湖相的粘土-藻白云岩-硅质白云岩组合中,受平行不整合面和褶皱的层间破碎带、裂隙密集带、断裂等控制,为典型的沉积改造型矿床;矿床经历了沉积和改造两个成矿期,即在麦地坪段沉积过程中铅、锌初始富集形成矿源层,经后期热液叠加改造富集成矿,矿区具备大型铅锌矿床的成矿条件,找矿前景良好.

| Abstract: | Paoma Pb-Zn deposit occurs in tidal flat-laggoon-faced clay-alga dolomite-siliceous dolomite assemblage of Maidiping Member of Cambrian Series and is controlled by parallel unconformity,folded interformational cataclastic zones,fracture-concentrated zones and faults.It is a typical reworked sedimentary deposit.The two metallogenic epochs,ie sediments of Maidiping Member that was primarily rich with Pb,Zn as ore source bed and late hydrothermal overprinting and reworking that enrich it to be ore.According to the ore-forming condition here is potential for further exploration. |
