Abstract
Summary
The relative motions of lithospheric plates are traditionally regarded as spreading, subduction and transform. Surveying data show a much greater variety of combinations. Purpose of the work is to identify the complete set of possible relative movements of plates. A new methodological approach is used. It consists in the fact that it was analyzed the movement of both plates relative to their border. This approach required additions to the structural-geological terminology. It made possible to formalize the orientation of the plate movements. 8 variants for the movement of the plate relative to its boundary were selected. In combination with eight of the same variants of the opposite plate motion, 64 combinations are obtained. There are 36 unique variants of combinations. 8 of them are well-known, 4 reflect the variants of displacement of inactive boundaries, and 24 are new to geodynamic theory. For 18 new variants, areas of their modern implementation in different regions of the world are shown; 6 more variants have not been found yet. The obtained result allows us to proceed to the analysis of interaction of multidirectional mantle flows.
