摘要
柴达木盆地北缘盆地-造山带体系在西北地区有一定的代表性,盆-山耦合过程与成矿的研究是当代地质科学研究的热点之一。以盆-山耦合体系演化、铀矿化目的层改造作用、砂岩型铀成矿理论为基础,将柴达木盆地北缘划分成四大构造单元,讨论了主要构造运动时期的盆-山耦合特征,分析了盆-山耦合体系对侏罗系、古近系和新近系的改造作用,指出了该区的主要找矿类型。
Basin-range coupling evolution and mineralization is a hot topic in present geoscience. Basin-orogenic belt system in the northern Chaidamu Basin is a representative of basin-range coupling in Northwest China. Based on basin-range coupling system evolution, reconstructive effect of uranium metallogenic stratum, sandstone-type uranium metallogenesis, this paper divides the northern Chaidamu Basin into four tectonic elements at first. Basin-range coupling characteristics are discussed for the main tectonic mo...
