桃山—诸广铀成矿带花岗岩型铀矿成矿规律研究主要进展
|
摘要
桃山—诸广铀成矿带是我国花岗岩型铀成矿带的典型代表,该成矿带内发育了数个大型花岗岩型铀矿田,桃山、鹿井、下庄是其中的典型代表。根据相关文献的阅读和整理,对桃山—诸广花岗岩型铀矿的成矿规律进行了总结:桃山—诸广铀成矿带花岗岩型铀矿的产铀岩体为复式岩体,产铀花岗岩具陆内S型花岗岩特征,围岩与矿体形成的时代差异较大。各矿床受构造控制特征明显,构造是影响铀成矿的重要因素之一。产铀岩体的热液蚀变非常发育,往往具有大规模、大范围、类型丰富等特征,这些热液蚀变现象也是判别产铀岩体的重要标志。
Taoshan-zhuguang uranium metallogenic belt is the largest granite type uranium metallogenic belt in China, and it is mainly produced in the granitic fields such as Taoshan, Lujing, Xiazhuang. According to the related literature reading and sorting, Taoshan-Zhuguang type uranium deposit metallogenic regularity are summarized: Taoshan-Zhuguang metallogenic belt granite type uranium deposit uranium-producing rock mass for complex massif, uranium production has the feature of intracontinental S type granite, granite mineralization diagenetic time difference is big, the ore-controlling geological interface characteristics significantly. The structure is one of the important factors to control uranium mineralization. The hydrothermal alteration of the uranium rock mass is developed, and the important symbol of the identification of uranium rock mass is the large scale, wide range and type the whole of hydrothermal alteration.
