Abstract The work of 1∶200 000 regional gravity surveys has been carried out deeply for a long time in China, and a large number of prospecting anomalies have been delineated in previous study. How to analyze these gravity anomalies? How to discuss subsurface occurrence of geologic bodies, such as stock, dyke, dike, fault structure and ore-bearing formation which associate closely with mineralization in detail? It is urgent to break through these bottlenecks which relate to deep prospecting. The work of high precision gravity survey for complex and varied terrain is relatively late in China, and it is even blank in Guizhou province. In order to develop and implement regional geophysical survey and high precision gravity survey in metallogenic belt of Guizhou province, the testing work has carried out in the Daotuo polymetallic reconnaissance area of Songtao county basing on its prospecting mineral is the dominant mineral of Guizhou province. It is proposed that high precision gravity survey is effective for Datangpo type manganese deposits, which provides practical basis for high precision gravity survey in similar region.

Key words： Songtao of Guizhou high precision gravity survey fault basin Datangpo type manganese deposits Nanhuan Period
