The present paper describes the geopbysical prospecting method used in stereoscopic geological mapping of the Southeastern Hubei metallic ore district (the northwestern part of the Yangxinrock mass) and the geological ore-prospecting achievements thus gained. Through close coordination of geophy-sical and geological work and using integrated methods including gravity survey, magnetic survey and electrical sounding, the author obtained a series of new understanding in such aspects as the study of the structure and scape of the rock mass, the delineation of the ore-control structure and shape of the rock mass, the delineation of the ore-control structure and the ore prognosis. The stereoscopic geological map vividly exhibits the spatial geological characteristics of the Yangxin rock mass.The test on the ore-prospecting target area has demonstrated that geophysical prospecting is quite effective in stereoscopic geological mapping and can lead to accurate metallogenic prognosis.
