Abstract
Aiming at the unresolved issues in the exploration process of Fuyanshan area in Weifang,including the relationship between fault structures,geothermal display,and geothermal anomalies,thermal control structure,thermal reservoir layers,as well as the geological structure,thermal reservoir lithology,burial depth,geothermal gradient,water temperature,water volume of the geothermal anomaly area and so on,through remote sensing geological interpretation,geophysical exploration,geochemical exploration,hydrogeological investigation,and civil(mechanical)well water temperature investigation,two water temperature anomaly areas,Daliushu and Fushan,are discovered,the geothermal gradient is determined,and it is inferred that the Yishui-Tangtou Fault and the Tangwu-Gegou Fault are the main thermal conductivity and thermal control structures,and they form good thermal reservoir layers with thicker siltstone,sandstone,tuff,and basalt of the Qingshan Group of the Cretaceous,and the Wangshi Group of the Cretaceous,the Wutu Group of the Paleogene,and the Linqu Group of the Neogene;a geothermal model for Fuyanshan area is established through comprehensive geological analysis,and the geothermal resources are estimated.The main reason for the formation of geothermal in Fuyanshan area is the decay of radioactive elements in Earth's material,which generates heat and is transmitted to the karst fissure water of the geothermal carrier through two deep faults,ultimately forming the Fuyanshan geothermal anomaly.关键词
