Estimation of the stressed-deformed state of the Murmansk region geological basement in regard to the construction and economic human activities
This work has been carried out using methods of numerical modeling to locate weakened zones in the basement of the region, which formed during a long geological period. For this purpose, we have constructed quantitative models of the stressed-deformed state of the Earth's crust in the region considering its evolution. For the first time the structures have been determined within which, in the Precambrian mainly, a tectonic-magmatic activity concentrated and mobile-permeable zones developed. For the first time, we have found an interrelation between localities of deep fractures (activation areas) and the stressed deformed state of the Earth's crust caused by the action of regional tangential stresses. The provided research indicate the necessity of studying the general geological structure of the region and identifying setting areas of ancient deep deformation structures in the major industrial, road, hydraulic engineering and other construction.
