Geological Conditions And Metallogenic Regularity Of Molybdenum Deposit In Hongluoshan—wuzhishan Area

Hongluoshan-Wuzhishan area is an important metallogenic belt for Mo on the northern margin of the North China Block and is also the second largest Mo metallogenic belt in China. The deposit types mainly include porphyry tapes, porphyry–skarn tapes, skarn tapes and quartz vein tapes. Base on the results of the previous researchs, it selects the typical deposits as an entry point, then with the application of the basic principles of petrology, mineral deposits and REE geochemistry. It has a detail study to the regional geological setting of the molybdenum metallogenic belt, geological characteristics and ore-controlling factors, pointing out that the magmatic activity and fault structures are the main controlling factors. On this basis,according to the research of the rock mineralization and alteration types, combined with the comprehensive analysis to the establishment of indoor maps and the results of data-processing, summing up the regularity that the molybdenum deposit is controlled by the NE tectono-magmatic belt and it has a trending of horizontal or vertical distribution , this will play a guiding role in the future exploration work .
