Characteristics and Prospecting Criteria of Outer Contact Zone Granite Type Uranium Mineralization in Xiazhuang Ore Field
Outer contact zone granite type uranium deposit is an important type of granite uranium deposit.By studying the geological and geophysical characteristics of the outer contact zone in the eastern area of Xiazhuang ore field,the characteristics and ore-controlling factors of outer contact zone granite type uranium mineralization in Xiazhuang ore field were summarized based on the uranium exploration results in the area.It was suggested that the uranium mineralization in the outer contact zone of granite in Xiazhuang ore field was strictly controlled by"lithologic interface,structure and hydrothermal alteration",and the contact interface between granite and Cambrian strata,strong structural zone,superimposed hydrothermal alteration and radioactive anomaly zone are the main prospecting signs.At the same time,it was considered that the Zhuyuantou area has similar metallogenic conditions and uranium mineralization characteristics to Xinqiaodong and Pingtian deposits,and highly profitable uranium mineralization has been discovered by the drilling in the concentrated areas of prospecting indicators,indicating that Zhuyuantou area is a key area for further uranium exploration.
