Anorthosite is an intrusive igneous rock characterised by mostly plagioclase feldspar. The top pictures two sample of Anorthosite found on earth, and the bottom pictures anorthosite samples from our Moon.
The reason the moon samples seem much lighter and broken up is because of all of the impacts our Moon has dealt with over millions of years, turning the rock into the fine white dust we know today.
I have more moon samples on the way. :)
