The scheme of geodynamic process during the production of granite-greenstone area (GGA) of the Middle Dnieper mega-block (MDMB) of the Ukrainian Shield has been presented. It reflects the change of the lithosphere thickness during activation lasted from 3.2 to 2.8 Ga ago. Composition of fluids accom...
