Analysis on metallogenic conditions on uranium deposits in Shuangqiao-Xinlu area

Based on the early research results, the major control factors of hydrothermal uranium deposits which include uranium source, structure, U-bearing host-rocks, wall-rock alteration etc. are studied in this paper to summarize and analyze the metallogenic characteristic and control pattern of Daqiaowu, Baihuyan and Yangmeiwan Deposits. These deposits are different in U-bearing wall- rocks, but they are similar in alteration types of wall-rock, and especially in controlling structure. According to these, the typical metallogenic model of hydrothermal uranium deposit has been built in research area and laid a base for model prospecting, prediction and evaluation.
