Based on metallogenic features and factors of the Guilinggou molybdenum deposit in Zhen' an county, the magmatic rock mass, structures, occurrences and size of the molybdenum mineralization zones in the mineralized area are controlled by regionally structural-magmatic zone at northeast trend in the Tongguan-Zhashui-Ningshan region; the secondary fractures in this area formed favorable storage spaces for accumulation of metallogenic materials ; intermediate-acidic magmatic activities and hydrothermal alternation ruled migration and accumulation of metallogenic materials ; the regional structural-magmatic zones at northeast trend in this area is of good ore prospecting potential, to which it should be paid much attention by geologists who are interested in ore prospecting in this area.
