Using Raman spectroscopy, quenching crusts from mid-ocean ridges have been studied. This experimental method permits identification of the crystalline or amorphous state of a substance. It has been revealed that a decrease in the efficient rate of quenching of matter from periphery to core of a sample leads to the appearance of a disseminated crystalline phase. The characteristic size of the glass structural inhomogeneities, ~2 nm, has been estimated by low-frequency Raman scattering.
