摘要：In order to explore and develop geothermal resources in Juxian area, Shandong Province has studied the causes of geothermal in Juxian area. On the basis of field investigation, drilling and logging, and water quality inspection in Juxian area, the metallogenic conditions were analyzed from the aspects of geothermal source, geothermal storage, caprock, and geothermal channel formed by geothermal water, and finally the geothermal causes in Juxian area. The surface water and atmospheric precipitation in the study area infiltrated through the fault near the Yishu fault, and after 3,150 m deep circulation, the heat was obtained by the normal geothermal heating method, while dissolving the mineral components in the surrounding rock, and finally gathered in the Qingshan Group andesite, It forms high-quality hot mineral water rich in minerals such as fluorine, strontium, lithium, metaboric acid and metasilicic acid. The andesite caprocks of the Qingshan Group effectively hindered the loss of the geothermal water and heat energy of the geothermal water gathered here. The geothermal water enters the geothermal well through faults and strata dissolution holes, and surges up to the surface.
