双桥—新路地区铀矿成矿条件分析

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

在前人研究的基础上,以铀源条件、构造条件、含矿主岩、围岩蚀变等热液型铀矿的主要控制因素为研究内容,较详细地总结和分析了大桥坞矿床(671)、白虎岩矿床(670)和杨梅湾矿床(621)及部分铀矿化点的成矿特征和控矿规律。发现各矿床(点)的含矿围岩虽然不尽相同,但围岩蚀变类型相近且构造控矿特征尤为显著,以此为依据构建了研究区典型铀矿床成矿模式(热液型),为后期借助模式找矿、预测评价等奠定了基础。

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 ty...
