本文以卫星图象信息为依据,结合野外调研,提出并确定了华北块体北缘存在:块体缝合线,褶皱-逆掩断层带,后孤碰撞带(断裂带),台槽过渡带,岩浆弧,以及燕山-喜山期的NNE向岩浆活动带、断陷带(断陷盆地)等双重构造的新认识。并在此基础上,对华北块体北缘与深成岩浆岩,燕山期岩浆活动带(包括火山岩带)有关的铀矿化作用的独特构造环境及“岩浆”型,断陷带中和面型等主要铀矿床成矿模式和铀成矿带的划分及其划分依据作了研究和探讨。并以铀矿床的实例作为佐证。
Based on the satellite image information and the field investigation, this paper proposed and confirmed the existence of the northern margin of the North China block: block suture, fold-inverse overthrust zone, post-solitary collision zone (fault zone) Magmatic arc, and NNE to Yanshan-Himalayan magmatic activity zone and fault zone (faulted basin). On this basis, the unique tectonic setting of uranium mineralization related to the deep plutonic rocks and Yanshan magmatic activity belts (including volcanic belts) in the northern margin of the North China block and the tectonic setting of “magmatism” type, fault zone neutralization type And other major uranium metallogenic model and uranium metallogenic belt division and basis for the division made a study and discussion. And uranium deposit as an example of evidence.
