摘要
旬阳锑汞矿田位于陕南旬阳县境内,是我国著名的四大汞矿基地之一。该矿田以公馆及青铜沟矿为主,还有香竹沟、大槽、大寨子、砂铜沟、竹筒沟、马鞍寨、马家沟、回龙、洛河、高花沟等矿床(点),矿区面积达280km2。本研究区锑汞的成矿受宁陕-旬阳-山阳大型帚状构造控制。矿体赋存于中、下泥盆统白云岩、灰岩中,锑汞矿化受构造岩带制约,成矿类型属沉积再造型,成矿期为燕山期。
As one of the four large Hg ore producers in China, the Xunyang Sb-Hg ore field is located in southern Shanxi province. Besides the Gongguan and Qingtonggou deposits, there are Xiangzhugou, Dacao, Dazhaizi, Shatonggou,Zhutonggou, Maanzhai,Majiagou,Huilong,Luohe and Gaohuagou deposits (occurrences) within the 280 km 2 area. This ore field is controlled by the Ningxia-Shanxi-Xunyang-Shanyang large brush structure, and the orebodies are hosted in Middle and Lower Devonian dolomite and limestone.These deposits were formed in Yanshannian by sedimentary-reworking.
