Evaluation Of The Stressed Deformed State Of The Earth's Crust In The Northeastern Part Of The Baltic Shield In The Late Archaean

摘要

The large amount of research data from the northeastern part of the Baltic Shield allows us to use this region as a reference site for reconstruction of the formation conditions of the Earth's crust. However, the mechanisms of the formation of Precambrian Earth's crust remain an object of discussion. This work is based on numerical modeling allowed us to distinguish the dependence of the formation of permeable zones in the crust on the natural stresses in the region. The results are presented for the first time (including quantitative estimates and relations between geological factors). They demonstrate the capabilities of the formation of deformation structures in the region and reflect the peculiarities of the tectonic evolution in the region, among which the main one is inherited properties of geodynamic activity in the regions from the Early Precambrian.
