Gonghe-Guide basin and its alternate mountains have characteristics of large basin conduction type geothermal resources geothermal gradient, existence of granite in geothermal drilling basement at several places, and zonal distribution of basin edge mountain uplift-fracture-convection type hot springs with high water temperature. At present, there are controversies concerning heat mechanism. The authors query the argument of the mantle type heat source, and hold that the granite radioactive heat is the geochemical basis of the earth's crust internal heat source. In addition, the authors use geothermal drilling temperature measurement curve and geochemical geothermometer to predict geothermal reservoir temperature and depth. It is held that this is a meso-low temperature system. Finally, the geothermal gradient calculation problems and geothermal system are discussed.
