on a synthetic study of density as well as magnetic and electric properties of rocks, the authors hold that the general Cenozic basement can be determined by gravity anomaly inversion, and that Archean and lower Proterozoic crystalline basements can be located with the help of aeromagnetic anomalies. A detailed study was carried out on the vertical distribution of Cenozic, Mesozoic and Paleozoic strata by using MT information. A study of Shijiazhuang depression revealed a low uplift, which is favorable for geothermal prospecting in Cambrian and Ordovician limestone. Two deep depressions in NS and EW directions were also detected in Shijiazhuang City. One is from the Railway Station to Yongbi and the other is from Yongbi to Ershilipu.
