Аннотация:
Based on the hypothesis advanced by S. P. Gabuda that the SiO2 molecule could undergo a transition from the linear form to the isomeric form with a ring-shaped (bent) structure, an idea is proposed that when the mantle substance melts, a phase transition of the bent SiO2 form into the linear SiO2 form can occur in the lower mantle. This phase transition might be of great importance for the lower-mantle convection processes and also for the rise of mantle plumes carrying both heat energy, and broad range of platinum group and rare elements to the Earth surface. © 2016, Pleiades Publishing, Ltd.
