The Bahe Valley in the eastern suburbs of Xi'an lies on the southwestern slope of Lishan faulted uplift.Using MT,seismic sounding and gravity survey,the authors made an integrated interpretation of the Cenozoic thickness in the surveyed area,inferred the character and cutting depth of the concealed fault,selected Cenozoic thermal reservoirs for the construction of geothermal wells.Drilling test proves that the geological effects are excellent.
