GNEISS. Ger. A rock resembling 

 granite in its constitution and ge- 

 neral characters; but it contains 

 more mica, and the colours are 

 banded, owing to the arrange- 

 ment of the minerals, especially 

 the mica, in parallel planes. In 

 consequence of this structure the 

 rock splits into coarse slabs, along 

 the planes of the mica, besides 

 having the cross fracture or cleav- 

 age of granite. It is often de- 

 scribed as a stratified or stratiform 

 granite. A rock intermediate be- 

 tween granite and gneiss is called 

 gneissoid granite. Gneiss is used 

 for building and flagging, (p. 25, 

 Book viii).
