| Xiaoqinling area is one of main molybdenum ore resources habitats in our country, having delivered Jinduicheng, Nannihu, Sandaozhuang, Shangfanggou ultra-large type molybdenum ore deposit and Leimengou and so on 10 molybdenum (tungsten) polymetallic ore deposit. The molybdenum reserves approximately composes the national ultimate reserves 52% (Zhang Zhengwei and so on, 2001). The research area is in Huaxian Xigou, which is lies in the Xiaoqinling ,Shannxi province, the geo-structure is located the south margin of North China plate, south adjoins with Jinduicheng hollow, north connects with the Weishui breaks, assuming east and west belt-shaped distribution.This article based on the new achievement of 1:10,000 regional geology minerals investigation in Huaxian Xigou in 2005. And studied the Xigou area different criterion shear zone distribution and the distortion characteristic, with the Xiao qinling area typical molybdenum ore the geological feature, concluded that the shear zone is Xigou area originate, the mineralization flows the character migration pattern, and proposed xigou area molybdenum ore origin pattern; The union remote sensing and quartz vein simple analysis, determined mineralized far scenic area and three points of the mineralized.The mainly achievement as follows:1.Confirmed the characters of the three (Wanggou-Miaoshang, Bingleng ditch-Cangjiaping and Yinsitai-Nantai) important structure shear zone in the research area, discovered in the area majority of molybdenum ores the quartz vein mops along the shear zone, the situation of granite crag bodies are obviously influenced by character of the shear zone. It is explained the three shear zones is the primary control factor to the molybdenum ore in xigou area.2.Determined the west ditch area shear zone spatial distribution and the scale; the system summarized its structure distortion characteristic. Indicated in the research area the shear zone overall take the crisp - tough detrusion as a characteristic. |
