[Abstract]:Geothermal is a kind of clean energy, which can be developed and utilized by means of hot springs and geothermal wells. The formation conditions, hydrochemical characteristics and isotopic characteristics of hot springs are analyzed, and the origin of hot springs is discussed. The research area is located in the northern part of Hebei Province and the northern part of Beijing, with a total of 5 hot springs and artesian hot water wells, including 13 springs in Tangzimiao Hot Springs, Chicheng County, Hebei Province. Hongtangsi Hot Springs, Fengning County, Yangshugou Geothermal well A26, Heilazi Geothermal well A30, and Tangquangou Hot Springs in Huairou District, Beijing, BHR200.The strata exposed in the study area include Archean migmatite, Proterozoic, Paleozoic, and Paleozoic. Mesozoic and Cenozoic sedimentary lithostratigraphy and Yanshanian granitic body. There are four deep and large faults in the study area: Shangyi-Chicheng deep fault, Shanghuangqi-Wulonggou deep fault, Fengning-Longhua deep fault and Chicheng Sunzhuangzi-Limestone normal fault. The lithologic types are complicated. The water temperature of the hot spring in the study area is 30.6-60 鈩，
