Hornblende Gneiss

Hornblende Gneiss

Gneiss is a widespread metamorphic rock that is medium to coarse grained and often contains significant amounts of quartz and feldspar. In most other regards, gneiss is quite various and, therefore, is often named based on certain characteristics, such as parent material or mineral constituents, in order that samples of the rock may be more explicitly identified.
