【摘要】 根据地球物理资料,郯庐断裂带(与合肥盆地接触的部分)平面上是一个破碎带,宽度约22km,断裂带内地层与两侧的下扬子陆块、华北陆块的地震反射特征和电性特征均存在较大差异,郯庐断裂带具有明显的分界特征.在横剖面上郯庐断裂带显示正花状构造,由一条走滑主断裂和几条平行的伴生断裂组成,其中主断裂断面直立,一直延伸到地下15km深处,仍未见消失或变缓的趋势,是压扭性断裂的典型特征.更多还原

【Abstract】 According to electric and seismic data, Tanlu Fracture Belt is a crushed zone and is 22km wide horizontally. There are great differences in seismic reflective and electric features among Tanlu Fracture Belt, Xiayangzi Block and North China Block, Tanlu Fracture Belt has the obvious demarcation feature. On the cross profile, it presents a positiveflowerstructure, and consists of a main slipstrike fault and several parallel associated faults, in which the main fault plane is vertical and extends down 15 km and still shows no tendency of disappearance and flattening. This is the typical feature of a compression fault.更多还原
