东北地区铀矿床类型空间变化的地质内涵及对铀矿找矿问题的思考

简述了东北地区铀矿成矿区(带)的研究成果,并对比了辽宁高家沟、连山关、赛马,内蒙古广兴元、红山子、钱家店,河北沽源、干沟等铀矿床类型,深化了"铀成矿(亚)类型随着区域地质历史的演变而发生规律性变化"的地质内涵;从铀矿成矿谱系的角度出发,指出"铀元素在同一成矿区(带)内长期聚集"是区域铀成矿的根本要素。并认为大兴安岭多金属成矿带和燕辽铀成矿带一样,具有寻找铀矿的巨大潜力,只要开拓找矿思路,立足于攻深找盲,一定会取得铀矿找矿的新突破。

Consideration on geological connotation of spatial pattern of uranium deposit types and their prospecting in Northeast China

The study on uranium metallogenetic region(belt) in Northeast China is briefly presented in the paper,the geological connotation that uranium metallogenetic types(sub-type) change regularly with the evolution of regional geology is deepened by the comparison of uranium deposit types in differrent areas,such as Gaojiagou Deposit,Lianshanguan Deposit,Saima Deposit in Liaoning Province,Guangxingyuan Deposit,Hongshanzi Deposit and Qianjiadian Deposit in the Inner Mongolia Autonomous Region,Guyuan Deposit and Gangou Deposit in Hebei Province.In the way of uranium metallogenetic series,the essence of regional uranium metallogeny is "the long-term concentration of uranium in the same metallogentic region(belt)".It is considered that Da Xing'an Mountain polymetallic metallogenetic belt has the same great potentiality for uranium prospecting as Hebei-Liaoning uranium metallogenetic belt.New breakthrough of uranium prospecting should be achieved on condition that new idea is applied and the prospecting is rooted in searching blind type and capturing buried deposit.
