Abstract:

The paper contains two parts：(1)In the research of the Quarternary active fault in theoverburden area in Shanghai,the author discussed and combined the research methed of geophysical(electromagnetic frequency sounding and shallow seismic exploration)and geochemical(fission track and Rn,Hg,As,Sb,Bi,B)approaches because of the thick overlying strata(maximun thickness 480m,average thickness 240m)and has gained satisfactory results.Themethed is valid for researching Quarternary active fault in the study area.(2)The existence ofthe Quarternary active fault in Shanghai overburden area is confirmed for the first time. Thetime these faults underwent the activity is Early Pleistocene.The basic characteristics and the activity of the Quarternary active faults has been discussed as well.

Key words: Overburden area, Quarternary, Active fault, shanghai
