Definitions and meanings of "Gneiss"

What do we mean by gneiss?

A banded or foliated metamorphic rock, usually of the same composition as granite. noun

A rock which consists essentially of the same mineral elements as granite, namely orthoclase, quartz, and mica, but in which there is a more or less distinctly foliated arrangement of the constituent minerals, and especially of the mica. noun

A crystalline rock, consisting, like granite, of quartz, feldspar, and mica, but having these materials, especially the mica, arranged in planes, so that it breaks rather easily into coarse slabs or flags. Hornblende sometimes takes the place of the mica, and it is then called hornblendic gneiss or syenitic gneiss. Similar varieties of related rocks are also called gneiss. noun

A common and widely-distributed metamorphic rock having bands or veins, but not schistose. noun

A laminated metamorphic rock similar to granite noun

A common and widely-distributed metamorphic rock having bands or veins, but not schistose.

Trincheras, giving birth to very hot springs (from 90. 5° centigrade), appears from the inclination of its layers to be superposed on gneiss which is seen further southward in the islands of the lake of Valencia; but conjectures of superposition founded only on the hypothesis of an indefinite prolongation of the strata are doubtful; and possibly the granite masses which form a small particular zone in the northern range of the littoral Cordillera, between 70° 3′ and 70° 50′ longitude, were upheaved in piercing the gneiss. ❋ Unknown (1851)
