NEOTECTONICS AND SEISMICITY OF YAN-HUAI BASIN IN HEBEI PROVINCE |

| Abstract: | The Yan-Huai basin consists of four minor basins, namely, Yanqing, Huailai, Zhuo-lu and Fanshan basins. This region has been subjected to a progressive subsidence since Neogene. It may be regarded as a typical region for seismogeological study owing to great development of Quaternary sediments, sharp contrast in relief, concentration of historic earthquakes and distinct neotectonic movements.Six neotectonic categories may be recognized in the region under study basing upon the sedimentary histor |
