【摘要】 黄陵断穹位于扬子准地台中段北部,为铅、锌重要成矿区,震旦系灯影组对铅、锌成矿起到了重要的层控作用,局限潮下相和滩缘相是铅锌聚合的有利岩相古地理条件,成岩期及后期改造作用是矿化富集的重要因素。根据成矿地质条件,该区圈定出二个Ⅳ级成矿远景区、五个Ⅴ级矿田(预测区),可作为今后工作部署的重点。更多还原

【Abstract】 Located in the north of the middle Yangtze paraplafform, the Huangling faulted dome is an important metallogenic area for lead -zinc ore deposit, which is controlled by the Sinian Dengying Formation. The most favorable environment for the deposit is sublittoral zone. And the ore enrichment happened during diagenetic stage and reformation later on. 2 Ⅳ -grade metallogenic area and 5 Ⅴ -grade ore fields have been delineated, where need further investigation in the future.更多还原
