Since this is not my area of expertise, I searched Google under the key words "granite" to get these possible sources:

http://en.wikipedia.org/wiki/Granite
http://www.fi.edu/fellows/fellow1/oct98/expert/granite.htm
http://volcano.und.edu/vwdocs/vwlessons/lessons/Rocks/Rocks10.html

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search.

I hope this helps. Thanks for asking.

Also on the uoregon site is AskGeoMan, which has answers to many geology questions.
Easy to find by typing AskGeoMan into Google.
