What is Gneiss? Gneiss is a foliated metamorphic rock identified by its bands and lenses of varying composition, while other bands contain granular minerals with an interlocking texture Other bands contain platy or elongate minerals with evidence of preferred orientation It is this banded appearance and texture - rather than composition - that define a gneiss...
