摘要
阐述了黑水地区区域构造新构造运动的演化特点,提出了目的层——孙家湾组沉积洼陷控矿和地下水的补-径-排主要通过断裂系统来完成,两组断裂交汇处为地下水从径流向排泄的转换部位,也是铀富集成矿部位。
Evolutionary characteristics of neotectonic movements of regional tectonics in Heishui area are elaborated. It is suggested that the ore-control by sedimentary depression and the recharge-runoff- drainage of the groundwater are realized mainly through the fractural systems. The transitional part from runoff to drainage of the groundwater lays in the intersection of two-group fractures and is also the position where uranium enriches to mineralization.
