摘要
Tianjin Fault includes south Tianjin Fault and north Tianjin Fault. Based on the results of artificial seismic exploration, four borehole profiles were laid out respectively to implement the exploration of these faults. Through identification of microfossils, the locations of marine strata in boreholes were obtained and through stratigraphic dating, the ages of the first, second and third marine strata were determined. The activity of the south Tianjin Fault is stronger than that of the north Tianjin Fault.
