Dongping tungsten deposit,located in northern Jiangxi province's Wuning County, is a new discovered super-large quartz-vein type wolframite deposit. According to the geological characteristics of the area and ore deposit, the major, minor and rare earth elements are analyzed respectively, and the regional and prospecting directions are defined. The results show that the two mica granite of metallogenic parent rock can be defined as a high silicon high potassium calc alkaline peraluminous high differentiated S type granite. Omega (SiO2) is 74.41%~75.63 %, omega (Na2O+K2O) is 7.69 %~8.11 %, and A/CNK is between 1.15 and 1.25. With the following characteristics, enriched light rare earth, heavy rare earth loss, strong negative europium anomaly (delta Eu is 0.20~0.34), the distribution curve of rare earth is right deep"V"type.%东坪钨矿位于江西省武宁县,是赣北地区新发现的超大型石英脉型黑钨矿床.根据区域及矿床地质特征,分别对主量、微量及稀土元素进行了分析,并划定了区域及找矿方向.结果表明:成矿母岩二云母花岗岩属高硅高钾钙碱性过铝质高分异S型花岗岩,w(SiO2)为74.41%~75.63%、w(Na2O+K2O)为7.69%~8.11%、A/CNK介于1.15~1.25之间,轻稀土富集,重稀土亏损,强负铕异常(δEu为0.20~0.34),稀土配分曲线呈右倾深"V"型,是华南中元古代基底的富泥质岩石重新熔融的产物.
