For some reason, I cannot find the links to the RSPOD for June 9th and June 10th. I never received the link in my usual emails and it's not in the archive yet. As soon as I get them, I will repost them here.
Meanwhile, here is the latest - a nice cross polarized microscope photo of the angrite D'Orbigny. I have a piece of D'Orbigny in my personal collection.
