Abstract
As a resulting of comprehensive studies of Paleoproterozoic igneous complexes a regular remagnetization trend is revealed. It is shown that the remagnetization front propagated from the northwest to southeast. The obtained remagnetization trend probably reflects the direction of the collision in the Paleoproterozoic. Correlation between remagnetization processes and rock compositions was found. The degree of conservation of secondary earlier and later magnetization components is likely associated to both the compositions of protoliths and different transformation conditions of rocks, including their fluid saturation.
