Characteristics of thrust nappe structure and geothermal prospect in the Chongli and Chicheng area
This paper is the result of geothermal geology.[Objective]This paper summarizes the upland belt heat reservoir in the Chongli and Chicheng area,which can be used as a reference for geothermal investigation in similar exploration areas and provide a new basis for geothermal resource exploration in the future.[Methods]Based on field geological survey and structural mapping,combined with the results of Controlled source acoustic magnetotelluric(CSAMT),the characteristics of thrust nappe structure and the prospect of geothermal exploration in the Chongli and Chicheng area are analyzed.[Results]Field geological survey and structural mapping revealed the overthrust and nappe structure in the Chongli—Chicheng area as well as buried and folded the Archeozoic and Paleoproterozoic Erathem and Cretaceous in the foot wall.There are typical zonation and stratification of thrust nappe structure.Preliminary results from Controlled source acoustic magnetotelluric(CSAMT)sounding validate the thrust nappe structure and the fault inclines to the north with a dip Angle of more than 60 and converges deep into the main floor thrust fault.[Conclusions]The discovery of the middle Proterozoic dolomite and the geothermal exploration prospect in this area has been expanded.
