Construction of Temperature Model along a Sublatitudinal Profile in the Chu Depression, Northern Tien Shan, Based on Seismic Tomography Data

Abstract—We propose a new approach to constructing a two-dimensional (2D) temperature model of the Earth’s interior based on solving the steady-state heat conduction equation with varying coefficients. To this end, using seismic velocity data measured on the sublatitudinal profile in the Northern Tien Shan, we built the lithotype model which was then employed to estimate the 2D distribution of thermal conductivity of rocks across the section with the allowance for its dependence on background temperature.
