摘要
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.
