| 摘 要： | 通渭—武都隐伏深大断裂为一近南北走向、隐伏的深部构造带 ,断面西倾 ,倾角约 6 0°～ 80° ,为高角度压性断裂。该断裂带发生于华力西期前 ,活跃于印支—燕山期 ,现仍处在活动期。断裂带两侧莫霍面深度、重磁场特征明显不同 ,带内岩浆活动强烈 ,是一重要的近南北向成矿带 ,也是一个现代活动带。

| Abstract: | The buried deep fault from Tongwei to Wudu is a concealed deep stractural belt,
strike approximate to N-S,dip W,dip angle 60°-80°,and that is a high-angle compression deep
fracture.It took place Variscan epoch ago,active moving during Indosinian to Yanshanian epoch
and so far it is still in active stage.The depth of Mohole and feature of gravity-magnetic field
have defference sharply on two sides of the fault belt.In the belt,magmatic action bein strong and
it is an important mineralization belt and a present-day active belt too. |
