If by useful you mean info on gneiss, it is basically a coarse-grained, foliated, high grade metamorphic rock. Gneiss forms during high grade, regional metamorphism, and can form from amny different parent rocks including shale and igneous rocks.

Gneisses are also named for the dominant material such as biotite gneiss or garnet gniess. - David Miller
