Favorite Thin Section Minerals

(Just because I can:  These are my favorite minerals in thin section.  What is a thin section?  It's when you glue a rock to a microscope slide and then grind it down to super super thin, so that light can go through the minerals.)


Clinopyroxene


Olivine


Amphibole


Plagioclase


Epidote and Dolomite
