I Love Granite...Plutonically (Dark) T-Shirt
- from our Affiliates
Declare your (plutonic) love for granites with this silly geology t-shirt! This triangle is a QAP diagram, used in geology to identify plutonic igneous rocks by name, based on the modal percentage of the component minerals Quartz, Alkali Feldspar, and Plagioclase! The text can be customized, as well. You could change it to "I Love Geology!" or "I Love Tonalite!" or whatever your favorite pluton happens to be.
