The Geothermal Study of the Mid-Segment of the Tancheng-Lujiang Fault Zone and Its Neighboring Region

摘要

In this paper, 25 new terrestrial heat flow values newly observed along the mid-segment of the Tancheng-Lujiang fault zone are listed. With these geothermal data and 37 other terrestrial heat flow values (previously published), we describe the distribution features of terrestrial heat flows in the area. In this research, the two-dimensional temperature structure from the surface to lithospheric bottom of the Huaibei-Sixian-Jinhu profile is inferred by using the finite-element method and the temperature and heat flow of sedimentary, granitic, and basaltic layers is calculated.
