“This is a series of closeup photos of a double-sided plate. The front side (this photo) has gemmy, pale blue fluorapatite with milky siderite. The back side (see last photo) has siderite on muscovite, both covered with small balls of marcasite. ”

“Stereo view of the same area as the parent photo, but at a different angle. Collection and photo, T. Peterson. ”
