摘　　要：安徽省宿松地区位于大别造山带东段南缘,该区地质构造复杂,变质作用强烈,是寻找沉积变质型矿产较有潜力的地区。本文通过分析宿松地区成矿地质背景、磷矿资源特征及分布规律,认为宿松磷矿属“海州式”沉积变质型磷矿,矿体赋存于中-新元古代宿松岩群的柳坪岩组和虎踏石岩组,磷矿的产出严格受地层和构造控制。通过化探成果分析以及典型矿床深部成矿条件研究,认为宿松地区深部仍具有较大的找矿潜力。The Susong area of Anhui Province is located on the southern edge of the eastern section of the Dabie Mountain orogenic belt,where geological structures are complex and intensely metamorphosed.It is an area with good potential to find metasedimentary ore deposits.By analyzing the metallogenic geological background,characteristics and distribution law of phosphate resources in the Susong area,it is believed that the phosphate is the"Haizhou-type"metasedimentary ore,and the ore body exists in the Liuping and Hutashi formation complexes of the Middle-Neoproterozoic Susong group complex.The occurrences of the phosphate deposit is strictly controlled by strata and structures.Through the analysis of geochemical exploration results and the study of deep mineralization conditions of typical deposits,it is believed that the deep part of the Susong area still has great prospecting potential.
