At least 3 large Phlogopite "books" are partly embedded in the calcite matrix of this specimen. These books appear to be in good condition, though one of the larger ones is obviously cleaved, and have good monoclinic and pseudohexagonal tabular form, with relatively well-defined edges and moderately clean faces. They are essentially black in color but have visible brown highlights. They are completely opaque, but the platelets that form the books are at least translucent as individuals, if not transparent. The books are accompanied by several green apatite crystals that are embedded in the calcite matrix- most of these are broken and intergrown with each other, but there are several which appear to be intact and in good condition. They have reasonably good hexagonal form, though their edges are all rounded, and are transparent and relatively clear, though usually internally fractured. These are some of the largest Phlogopite crystals that we have seen available.
