METALLOGENIC CONDITIONS FOR THE URANIUM DEPOSITS IN LIULIN AREA, XINYANG, HENAN PROVINCE

The Liulin area, located in the junction of the North China platform and Yangtze platform in the west part of Lingshan intrusion, belongs to the Tongbai-Dabie fold belt of Qinling fold system. This area, with frequent magmatic activities and developed faults, is a high radioactive field region with favorable geological conditions for the mineralization of uranium and polymetallic deposits. The major controlling factors of hydrothermal uranium deposits are studied to analyze the metallogenic characteristics. A typical metallogenic model for the uranium deposit in the studied area is set up. It can be used to guide further exploration for the same type of uranium deposits in the area.
