江西省大余县青石钨矿区地质特征

Geological characteristics of Qingshi tungsten deposit in Dayu County, Jiangxi

矿区位于华南褶皱系赣中南万洋山～诸广山复式向斜西南段,南岭东西复杂褶皱带东段。以大脉型和云英岩石英脉带型两种类型钨矿产于九龙脑花岗岩体内接触带中。本文通过对地质特征和矿石矿物的分析,对区内成矿地质特征进行叙述。

the mining area is located in the southwest section of the wanyangshan - zhuguangshan compound syncline in the south China fold system and the eastern section of the east-west complex fold belt in the south ridge. Two types of tungsten minerals, large vein type and yun ying rock English vein type, are found in the contact zone of jiulongnao granite body. Based on the analysis of geological characteristics and ore minerals, this paper describes the geological characteristics of mineralization in the area.
