Аннотация
From the structural peculiarities of lavas from ocean floor which was sharply cooled under high pressure of silicate melt fixed were moments of initiation of liquation, i. e. presence of emulsions of non-mixing fluids. This process is due to high volatiles present in differentiating magmatic melt, which is confirmed by high water content in he derivatives of such a differentiation, i. e. in crystalline augitic lavas of alkaline-ultrabasitic composition
