| 摘 要： | 狼山—武威—共和断裂带是近年来根据重力、航磁资料解释发现的规模仅次于郯庐断裂的大型走滑隐伏断裂带。该断裂带沿狼山—武威—共和一线呈NEE向延伸 ,横切了北大山、龙首山、祁连山和西秦岭造山带 ,使蒙甘青地区在地球物理场和区域构造格架上具有EW分块的基本格局。沿该断裂 ,温泉、地热异常成群、成带分布 ,与其南段亚东—羊八井—那曲走滑断裂 ,构成中国西部一条近SN向导热、控震断裂构造。

| Abstract: | The discovery of Langshan-Wuwei-Gonghe faulted zone is on the basis of explanation of gravity and aeromagnetic data in recent years,its scale is only smaller than Tanlu faulted zone and belongs to big burried strike-slip faulted zone.The faulted zone extends NEE along Langshan-Wuwei-Gonghe and transect Beidashan,Longshoushan,Qilianshan, West Qinling orogenic belts,and it made the geophysical fields and regional tectonic framework in Nei Monggol, Gansu and Qinghai showing EW segmentation.Along this faulted zone,distribution of thermal springs and geothermal anomalies is as in group and zonation,and together with its southerm part,Yadong-Yangbajing-Naqu strike slip fault made up a SN faulted structure of heat conductivity and controlling earthquake in west China. |
