摘要
应用物、化探相结合的方法，首次证实了广为第四纪松散沉积层（平均厚度达２４０ｍ）所覆盖的上海地区存在着第四纪活断层，并对其基本特征和活动情况作了初步论述。
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 geo-physical（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 ac-tivity of the Quarternary active faults has been discussed as well.
