Through analysis on geological data,it is regarded that there are good forming environment and occur-rence conditions of geothermal in this area.Focusing on both sides of Tangwu-Gegou fault belt,by using geolog-ical survey,temperature measurement,geophysical exploration,drilling and other means,geological conditions of geothermal have been surveyed and analyzed.Chunyu geothermal and Liangjiazhuang geothermal anomaly zone have been circled.After analysis,it is determined that the heat source is initially deep crustal heat flow,and ther-mal conductivity water channels are Tangwu-Gegou fault and its secondary faults.Thermal reservoir is deep con-vection and ribbon type.lithology of geothermal reservoir is andesite in Cretaceous Qingshan group with the depth of 1400~2000m.Its covering layers are Neogene,Paleogene and Cretaceous claystones and sandstones.Combi-ning with regional geological data,a conceptual model of geothermal resources has been set up,and location and hole depth of three proposed wells have been accordingly determined.
