摘　　要：西湾铅锌矿是庐枞盆地北部边缘三叠系中统东马鞍山组中发现的大型隐伏铅锌矿床。矿体主要赋存于东马鞍山组角砾状灰岩中,受北东向基地断裂和东西向基底(膏岩)隆起控制。本文总结了区域成矿地质背景和矿床地质特征,分析了控矿因素,探讨矿床成因和找矿方向,为该区下一步的找矿工作提供指导意义。Xiwan lead-zinc deposit is a large concealed lead-zinc deposit discovered recently in the north margin of Luzong volcanic basin.Ore body occurring mainly in the breccia limestone of the basement strata-triassic Dongma Anshan formation.This paper summarizes the regional metallogenic geological background and the geological characteristics of the deposit,analyzes the ore-controlling Factors,discusses the Genesis of the deposit and the prospecting direction,and provides guidance for the next prospecting work in this area.
