Siderite with Quartz and Arsenopyrite (Ref: NY13AB1)

Minas da Panasqueira, level 0, Aldeia de São Francisco de Assis, Covilhã, Castelo Branco, Cova da Beira, Centro  Portugal
43mm x 33mm x 20mm
minID: TPK-MCX
Aggregate of prismatic Siderite crystals with pinacoidal terminations. They have a very uniform dark brown color and silky luster due to microcrystalline surfaces on the prisms. The Siderite is with a small matrix of Quartz and Arsenopyrite and has cubic Pyrite microcrystals on its faces. Unlike most Panasqueira Siderite, this sample lacks the typically dull creamy second generation, which makes it very showy.
