[Abstract]:The study area is located in Western Turkey and is located in the southern margin of the Eurasian plate. Since the late Oligocene to the early Miocene, the region was in a tectonic stress field extending back to arc due to the subduction of the African plate and the Arabia plate to the north of the region, and the subduction rate of the eastern Arabia plate was faster, making the crust of the study area. The continuous stretching of the north-south direction moves westward at the same time. The continuous stretching of the crust in the study area has been thinner and thinner, making it one of the regions with the most intense crustal deformation, active faults, most frequent earthquakes and one of the most abundant geothermal resources in the world. Geothermal energy is one of the most stable and clean energy in the new energy, which has become a domestic one in recent years. The geothermal power generation has the characteristics of reliable income and huge investment. It is very important for the research of the genetic mechanism of the hot field in the region, the investment decision of the geothermal power generation, the design of the installed capacity and the risk control. This paper uses the fast wave front propulsion ray tracing method and the subspace iterative algorithm to accurately retrieve the depth of the study area. The velocity structure of the crust and upper mantle above 40km is found, and it is found that there is a low velocity body in the deep 15-50km range of the study area. Combining with the regional magnetotelluric sounding data, it is deduced that the magma capsule is not completely consolidated, and the source mechanism of the western Turkey Aegean Sea area is solved by using the method of seismic source, and the type of seismic fault in the whole region is studied. On this basis, the fine seismic source mechanism of the key hot field area is solved. It is found that the seismic faults in the study area are mainly normal faults, and the SATSI program is used to accurately retrieve the present tectonic stress field of the study area. It is found that the stress state of the Denizli Basin in the study area is not uniform under the double action of North-South stretching and east to West extrusion. First, it is the main cause of earthquake occurrence in this area. Taking the Denizli basin as an example, the geothermal model is established by using magnetotelluric method, hydrogeochemical method and isotope geochemistry method, and the thermal reservoir, cover layer, heat source, water source and hot field parameters are discussed, and the system has been collected. The geothermal data of all hot fields in the field have drawn the geothermal flow chart of the study area, the geothermal gradient map, the temperature distribution map of the spring mouth and the distribution map of the thermal storage temperature. The geothermal anomaly distribution characteristics and laws of the study area are illustrated systematically, and it is found that the highest geothermal flow in the region is found in the area of the Qula volcano, which may be a new Neogene with the deep structure. The main channel of mantle material upwelling since the Quaternary; on the basis of the above, the geological origin of abnormal distribution of regional geothermal distribution, such as formation distribution and thermal reservoir distribution, volcanic activity and heat source of hot field, and the heat control mechanism of active faults on hot fields are systematically expounded, and the deep tectonic origin of geothermal anomaly distribution, such as crust mantle velocity, is discussed. The deep structure represented by the degree structure, the electrical structure, the deep and the gravity anomaly is systematically expounded, and the dynamic mechanism of the geothermal anomaly is systematically expounded. On this basis, the comprehensive genetic mechanism model of the geothermal anomaly has been established. The innovation point of this paper is the seismic tomography based on massive earthquake events, The fine inversion of P wave, S wave velocity structure and Poisson's ratio above the depth of 40km in the study area is carried out, and the spatial distribution of the underground magma capsule in the study area is fine depicted. The fine current tectonic stress field in the study area is established by the source mechanism, and the genetic mechanism and hot field properties of the Denizli hot field are studied. Collecting the latest geothermal data in the region and combining the situation of the hot field in the Denizli basin, the characteristics and laws of the geothermal anomaly distribution in the region are clarified, and the genetic mechanism of the geothermal anomaly distribution is systematically discussed from geological causes, deep structures and tectonic stress fields, and a comprehensive genetic model of geothermal anomaly in the whole of Western Turkey has been established.
