中文摘要：

大海铅锌矿床位于云南省会泽县南西，处于川滇黔铅锌成矿域滇东北铅锌成矿区南部，为近年来新发现的产于下寒武系渔户村组中的层控矿床。矿区北起泥者箐，南至下观音岩村银厂沟，长10km，呈南北向展布，由北而南划分为火石梁子、老林-石板沟和八角地-观音岩3个矿段。赋矿围岩为下寒武统渔户村组浅灰、灰白色中层至厚层状粉晶白云岩、硅质碎裂白云岩夹硅质岩，近南北向层间断裂控制了上、下2个含矿层的分布，北西向断裂控制了富厚矿体的产出。火石梁子、老林．石板沟矿段以上含矿层矿化为主，八角地-观音岩矿段以下含矿层矿化为主。本文通过综合研究矿床地质特征，提出矿化强度与含矿层、含矿层与顶板岩性差异、层间构造、叠加构造密切相关，通过对勘查程度较高的八角地-观音岩矿段的勘查经验分析了矿床的进一步找矿前景，并指出了下步勘查方向和合理的勘查手段。

英文摘要：

Dahai lead-zinc ore deposit, located in the southwest of the Huize County, Yunnan province, China, is tectonically situated in the southern part of the Northeast Yunnan lead-zinc mineralization district of the Yangtze metallogenic province. The mineralization of Dahai lead-zinc ore deposit is hosted in the sedimentary sequence of the Lower Cambrian Yufucun Formation. By integrated study on the geology of ore deposit, and combined with the comprehensive analysis of exploration results in recent years, it is concluded that Pb-Zn mineralization is significantly related with ore-bearing strata with differences between the ore-bearing rocks and the hanging wall of ore-bodies, as well as intrastratal structure and superposed fractures. The follow-up exploration targets were outlined and the proper exploration methods were proposed on the basis of analysis on previous exploration results on Bajiaod-Guanyingyan ore section with higher exploration level.
