This is one of only a few specimens that I have seen come from Portugal. This particular piece consists of a cluster of intergrown "books" of micaceous Autunite platelets. They are generally in moderately good condition, as there are a few substantial areas of damage. The platelets are small, not exceeding 0.2" (5 mm) in diameter, and have rather warped forms due to their intense intergrowth. They have a greenish-yellow coloration and a pearly luster, and are nearly opaqe, showing only a dim translucence at some points. There is a small amount of a dull, rust-colored host rock scattered about on the piece, but no other host material.
