| Abstract: | Shawan fault is an important fault zone of the Pearl River Delta region,and it is blind fault at most areas of Guangzhou.It is composed of a set of NW-trending faults,in which most of the fault plane dip to southwest. From Cenozoic Era on,there are 3-phased strong activities at least.It was a normal fault in early stage,changed to a reverse fault in middle stage,in the third stage it returned to a normal fault;it is still active in Quaternary. |
