江西省赣县黄婆地钨多金属矿矿床地质特征

Geological Characteristics of Huangpodi Tungsten Polymetal Mine, Ganxian in Jiangxi

摘要: 黄婆地钨多金属矿矿区位于北东向于山构造带与东西向崇义—会昌构造带的交汇部位。区内岩浆活动强烈而频繁，褶皱、断烈构造较发育。通过对黄婆地钨多金属矿区的地层、构造和岩浆岩等资料的研究发现，该矿主要存在于石炭系下统梓山组砂岩、细砂岩内及其与花岗岩的接触带附近，矿体类型有矽卡岩型白钨多金属矿体和石英脉黑钨矿体，其中似层状的矽卡岩型矿体为目前的主采矿体。

Abstract: Huangpodi tungsten polymetal mining area is located in the joint position of Yushan tectonic belt, NE, to Chongyi—Huichang tectonic belt, EW. Magmatic activity is frequent in this area; fold and fault also have good development. The research of the stratal, tectonic, magmatic and other data of Huangpodi tungsten polymetal mining area shows that the orebody mainly occurs in the sandstone, fine sandstone of lower Carboniferous Zishan formation and near the contact zone with the granite. There are two orebody types: one is skarn scheelite polymetallic orebody; another is quartz vein wolframite orebody. The layered skarn type orebody is the main body of mining at present.
