NZR47AN4: Group of large, very sharp rhombohedral Siderite crystals with a dark brown color, translucent on the edges and with small partial coatings of a second generation of Siderite with a lighter cream color. They are associated with leafy muscovite aggregates. We highlight the unusual fact that the first generation of Siderite is dominant in this piece, since in Panasqueira it is very rare that this first generation, with its darker color and a certain transparency, is not covered by a second generation of Siderite with a lighter color but much more opaque, which is what gives the siderites there their characteristic appearance.

NZ46E6: Very transparent crystals of Quartz. So you can see the well-defined crystals of Arsenopyrite and sprays of Mica inside it. They were trapped in it as the Quartz grew. The Quartz itself is a floater (with a recrystallized base) and has a totally undamaged tip, which is not that common in specimens from Panasqueira given the way they are collected. On the outside there are similar minerals to those inside: Mica and Arsenopyrite.
