Abstract: Dongping tungsten deposit is the first super large quartz vein type wolframite deposit found in the north of Jiangxi Province in recent years. It is located in the east of the prospecting area of Dongping-Xianglushan in the Mufu Mountain metallogenic belt in the middle and lower reaches of the Yangtze River. The ore bearing strata of the deposit are shallow metamorphic rocks in the Neoproterozoic Anlin group of Shuangqiao Formation. The north-east trending fault and its secondary fissures are the main ore controlling and ore bearing structures in the area. The concealed Late Yanshanian black mica granites are the ore-forming rock mass, and the quartz vein silicification is closely related to the tungsten polymetallic mineralization in the area. The tungsten ore bodies of the two ore belts occur in the contact zone of the ore forming rocks, showing the typical "five storey" zoning characteristics of the quartz vein type wolframite deposit, and wolframite ore is the main ore type. It is concluded that the mica-pyritization alteration zone, sulfide-bearing quartz vein zone, quartz vein, heavy sand and geochemical anomalies are the main prospecting indicators in this area.

Key words: quartz vein type wolframite, geological features of ore deposits, super large, Dongping tungsten deposit, northern Jiangxi
