GRANITE 



In the strict sense granite is an entirely crystalline igneous rock 

 made up of potash, feldspar and quartz, usually with subordinate 

 amounts of mica, hornblende or pyroxene. Among quarrymen and 

 builders, however, the name granite is given to various other types 

 of rocks, such as the heavier and darker colored diorites, norites, 

 gabbros, syenite which resembles granite but lacks quartz, and the 

 bedded or banded rocks known as gneisses and schists.
