摘　　要：凤凰山钨矿位于华夏板块南岭东段隆起带之罗霄-诸广隆起与吉泰断陷盆地交接部位,钨矿体赋存于隐伏花岗岩体外接触带寒武系下统牛角河组蚀变砂岩中,为细脉蚀变岩型钨矿新类型。细脉蚀变岩钨矿石由含钨蚀变岩和石英细脉两部分组成,钨的赋存状态主要为白钨矿,次为黑钨矿,蚀变岩内仅见白钨矿。矿床控制资源储量达中型以上规模,深部仍有较好的找矿前景。该矿的新发现,对赣中乃至华南地区钨矿找矿具有重要的指导意义。The Fenghuangshan tungsten deposit is located at the junction of the Luoxiao-Zhuguang uplift in the east section of the Nanling uplift zone of the Cathaysia plate and the Jitai fault basin.The tungsten ore body occurs in the lower Cambrian Niujiaohe Formation in the external contact zone of the concealed granite.Among the altered sandstones,there is a new type of veinlet altered rock type tungsten ore.Tungsten ore of veinlet altered rock consists of two parts:tungsten-containing altered rock and quartz veinlet.The occurrence state of tungsten is mainly scheelite,followed by wolframite.Only scheelite and no wolframite are seen in the altered rock.The controlled resource reserves of the ore deposit reach a medium-sized or above scale,and there are still good prospecting prospects in the deep part.The new discovery of this deposit has important guiding significance for the prospecting of tungsten deposits in central Jiangxi and even in South China.
