WebAnorthite. Anorthite is the calcic end member of the plagioclase feldspar series. In thin section, plagioclase feldspar grains often look like they’re sprinkled with dirt (PPL) or tiny confetti (XPL). You can find the explanation on the plagioclase feldspar page. Anorthite weathers quite readily, so it’s not terribly abundant on Earth.
