| Dongshan Tungsten ore deposit, lies in the Lingwu country of south of the Hunan province, is a Skarn- hydrothermal scouring replacement deposit, and scheelite is only useful mineral in this ore deposit.Basic on the host-rock and the host structure characteristics, the author determined the location mechanisms, analysised the geologic formation conditions, summarized the metallogenic regularities, then predicted the blind orebody through some kinds of methods and determined the geological background, the shape, occurrence, spatial distribution, extention and variations of sections, the relationship between occurrence of orebody and structure, the inner structural characteristics of orebody, the host structure and distribution in spatial, then to discover some rules of geological conditions and metallogenic regularities.We found out that the deposit related to structers closely. Orebody always occur at the low point of touch-zone. The orebody occurred in the concave of the touch-zone from steep to gentle. The observation under electron microscope to the sample affords the ore-forming mechanism. Indicator element in the geochemical prospecting plays an important role in prospecting the blind orebody in the deep. Prospecting with the IP sounding method find out the lower resistance and lower Cathode layer. Though analysise of the geological condition and metallogenic reglarities, then find out the prospecting area in the deposit.
