Dahutang tungsten is discovered in recent years, which is widely concerned because of various types of mineralization and unique metallogenic geological conditions, has been identified as large scale. It doesn't only change the "South-tungsten, North-copper" resource pattern, but also makes the research center transfer from south to north. Recent years, about this area much research work have been done and a lot of achievements are applied to the prospecting practice, playing an important role for the further expansion of the amount of resources. The breakthrough of Dahutang ore district overturned many traditional understanding of metallogenic theory in Jiuling area. The new discoveries of scheelite, cassiterite, stannite and sphalerite, especially the discovery of scheelite, changed the previous history of focusing on wolframite, with important reference significance for the future prospecting in the area of wolframite. On the deposit types, the altered granite type and hydrothermal cryptoexplosion breccia type tungsten polymetallic ore have been discovered, especially the veinlet disseminated and thick bedded scheelite ore body which occurs in the outer contact zone of Jinning biotite granodiorite, providing the new prospecting direction for Jiuling area. The district is located in the southeastern margin of the Yangtze plate, belonging to II grade tectonic units of Jiuling-Zhanggongshan west uplift of Jiangnan massif. It is adjacent to the nappe structure of Leping and Jiuling. 2 Regional Strata
