Source for information on flaser gneiss: A Dictionary of Earth Sciences dictionary. flaser rock (flaser gneiss) A rock displaying ovoidal megacrysts enclosed within a fine-grained, streaky, anisotropic groundmass. The groundmass is typical of a mylonite fabric produced by intense deformation. The megacrysts are regions of the original rock which have survived deformation.
