摘　　要：小韦村地区濒临宁芜火山岩盆地南西外缘,属宁芜铁硫成矿带延伸部位,区域断裂构造发育,燕山期岩浆活动频繁,成矿地质背景良好。经过前期地质工作发现小韦村铁矿床的主矿体呈层状、似层状,产于中三叠统徐家山组硬石膏层和黄马青组粉砂岩与闪长岩接触带部位,属于接触交代型和热液改造型多成因型铁矿床。The xiaoweicun area is near the southern margin of Ningwu volcanic basin, which belongs to the extension area of Ningwu iron-sulfur metallogenic belt, regional fault tectonic development, Yanshanian magmatic activity is frequent and mineralization geological background is good. After the geological work, the main orebodies of the xiaoweicun iron ore deposit are layered,which are found in Middle Triassic Xujiashan group of anhydrite formation and Huangmaqing group siltstone and diorite contact zone, belongs to the contact metasomatic type and hydrothermal reformation type polygenetic type iron ore deposit.
