English - English Definition of gneiss in English English dictionary A common and widely-distributed metamorphic rock having bands or veins {n} a compound stone of a fibrous texture a coarse, foliated metamorphic rock in which bands of granular minerals Layered Quartzofeldspathic Augen Gneiss and Flaser Gneiss (Proterozoic Y) at surface, covers 8 % of this area Leucocratic to mesocratic, mesoscopically-layered coarse-grained quartzofeldspathic biotite gneiss contains prominent polycrystalline quartz-feldspar augen within an anastomosing, mica-rich, schistose matrix. The resulting migmatitic gneiss is the most widespread rock of the area, and includes flaser gneiss, green-schist, and piedmontite-bearing gneiss as distinctive varietal types. Rocks of the San Jacinto Mountains south of San Gorgonio Pass are distinctly different from those to the north, and comprise texturally uniform granodioritic and Layered Quartzofeldspathic Augen Gneiss and Flaser Gneiss Leucocratic to mesocratic, mesoscopically-layered coarse-grained quartzofeldspathic biotite gneiss contains prominent polycrystalline quartz-feldspar augen within an anastomosing, mica-rich, schistose matrix. The flaser gneiss fades has coarse flaser, largely of quartz grains, and grades into the porphyroblastic. The eastern border fades is highly felsic and coarse grained, possibly an eastern transition into the Bolton schist.
