It should be realized that the peritectic reaction of ferrobridgmanite (the “stishovite paradox”) is of fundamental importance as the physico-chemical mechanism which provides the mere possibility of the ultrabasic-basic evolution of the lower-mantle magmatism. As this take place, the regime of fractional crystallization is able to provide continual changes in formation from ultrabasic to basic minerals at lower mantle conditions.
