Abstract
Xiaoliugou tungsten-molybdenum-copper-iron polymetallic ore deposit area consists of five tungsten-molybdenum-copper polymetallic deposits such as Yanqing, Xiaoliugou, Guishan, Shiji and Yubao, and four iron deposits such as Xiaoliugou, Guishan, Zhulongguan and Long'a. The composition of the iron ore deposit, except for the Xiaoliugou and Long' ayu iron ore mines, is produced in the Carboniferous Qianyun Qianyan and the Green Mudyun Qianyan, which are produced in the Xiayan Formation of the Jingtaishan Group in the Jixian County. The diagenetic mica volcanic schist, skarnized limestone and quartz veins of the upper and lower rock formations of the Zhulongguan group and their transition zones in the Great Wall. The genetic type of the deposit is a volcanic jet (gas) sedimentary (re) modeling deposit. The industrial type of the deposit is mainly quartz vein type, skarn type, fracture zone type, porphyry type, and the ore is mainly disseminated-densely disseminated white. Tungsten ore and densely disseminated scheelite-chalcopyrite ore. The formation and distribution of deposits are closely related to strata, structure and rock mass. The concealed magmatic (body) emplacement structure controls the type and distribution of deposits (points), and the sliding dislocation structure between the anticlines controls the scale, occurrence and morphology of the ore bodies. The lithologic interlayer structural fissures control the enrichment of ore-forming elements. In the next step of exploration, we should pay full attention to the overall study of different deposits, and find the blindness of the deep-seated as the first priority of exploration, and use the deposit and the periphery of the deposit as the key prospecting space to strengthen the matching components and other new types of mines.关键词
