| 摘 要： | 柴北缘盆地-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，将柴北缘划分四大构造单元，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休罗系、第三系的改造作用，指出了该区的主要找矿类型。

| Abstract: | The system of basin-orogenic belt on northern edge of Qaidam Basin is representative in Northwest China. The relationship between basin-mountain coupling process and metallogeny is a hot spot in modern geological research. Based on the evolvement of basin-mountain coupling, alteration on target bed for U mineralization, and metallogenic theory of sandstone-host U deposit, the study has plotted the north edge of Qaidam Basin into four major tectonic units, discussed the characteristics of basin-mountain coupling during the major period for tectonic movements, analyzed the alteration on Jurassic and Tertiary strata by basin- mountain coupling system, and pointed out the major prospecting types in this area. |
