| Abstract: | The global stress field appearing in the Earth’s lithosphere under the action of forces caused by the difference of gravitational
potential is calculated. An original algorithm is proposed and the operational Earth Stresses program code is developed. The
data on the topography, thickness, and density of the Earth’s crust and the upper mantle, as well as the gravitational anomalies
and thermal conditions in the lithosphere were taken into account in the calculations. A comparison of the calculation results
and the observed data makes it possible to conclude that the action of the forces of the difference of the gravitational potential
alone is sufficient to explain the features of the first order of the stress field in the Earth’s lithosphere. |
