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.
