The Shawan fault zone in the Pearl River delta consists of a group of NW-striking faults, discontinuously exposed and concealed. In the detection of this group of faults, the authors adopted the integrated geophysical-geochemical method comprising geophysical survey, shallow seismic reflection method and high-density electrical method as well as geochemical survey. Integrated survey was conducted for 4 concealed faults (Dawugang fault, Shawan fault, Chencun fault and Zini fault) which belong to the Shawan fault zone. During the detection, 7 anomalies were delineated, and geometrical information concerning the fault position was preliminarily obtained, thus laying the foundation for drilling verification.
