GRANITE 
Granite, in the strict sense, includes the coarser-grained igneous 
rocks which have quartz, feldspar and mica as their chief constitu- - 
ents. They are characterized by a massive appearance incidental 
to an even distribution of the mineral ingredients, though by com- 
pression during or after the period of consolidation they may de- 
velop a parallel arrangement, in which case the term granite gneiss 
is best applied to them. The feldspar of typical granite is an alkali 
variety, either orthoclase or microline, but some lime-soda-feldspar 
like oligiclase is usually present as well. Hornblende and more 
rarely augite may accompany the mica or substitute for it. The 
texture is even granular or porphyritic. 
The definition as given is rather narrow for commercial usage
