| A “Five-storey” Style Quartz Vein Wolframite Deposit in Northern Jiangxi Province: The Discovery of the Dongping Wolframite Deposit and Its Geological Significance |
| The surveying results obtained in the Dongping deposit of Wuning County in Jiangxi Province shows that the deposit is a typical “five-storey” style quartz vein type tungsten deposit. The scale of the deposit is very huge, with Early Cretaceous biotite adamellite being the mineralized body, and veined silicification being the main alteration in the ore district. Vertically, there is the zoning of zone→veinlets zone →thin vein zone→thick vein zone→pinch out zone in upward succession, and the first four quartz veins all occur in the outer contact zone of Shuangqiaoshan Group, with the giant vein pinch out zone developed in the rock. Wolframite and chalcopyrite are the mainly metallic minerals, whereas minor minerals include pyrrhotite, sphalerite, farsenopyrite, argentite, arsenic sulfide silver, bismuthinite, bismuthinite sulfur, and pyrite, with a small amount of chalcocite, scheelite, azurite and limonite. Comprehensive studies have shown that there exists a big potential of bedded mineral alteration granite type tungsten orebody between deep rocks and the inner contact zone of the rock, and that there might exist a similar deposit on the periphery of the ore district. The discovery of this ore deposit ended the history that there was no typical “five-storey” style quartz vein wolframite deposits in northern Jiangxi, and it is also an important ore deposit extending from the south to the north. The discovery of this ore deposit has an extremely important significance for prospecting breakthrough in northern Jiangxi. |
