The Panasqueira Gallery includes a number of specimens from the world-famous tungsten and tin specimen-producing mines of Panasqueira in central Portugal. There are three pages to browse with a variety of specimens such as apatite, siderite, arsenopyrite, quartz and others. |
WPAN-11 - Apatite, tourmaline and siderite on muscovite Barroca Grande Mine, Panasqueira, near Silvares (Fundao, Portugal) Floater mass of fine-grained silvery muscovite serving as a matrix for numerous lustrous green apatite crystals to 1 cm. across, doubly terminated arsenopyrite crystals to 0.8 cm., creamy tabular hexagonal crystals of siderite to 1 cm. across and a few tourmaline-included quartz crystals to 1.5 cm. long. The whole specimen is finally covered by lustrous thin acicular tourmaline neddles to 1.5 cm. long. Some bruising at the edges of the muscovite mass, otherwise undamaged. A very fine and interesting specimen. 11x5.5x4.5 - Sold |

WPAN-4 - Siderite and muscovite Barroca Grande Mine, Panasqueira, near Silvares (Fundao, Portugal) Group of creamy siderite crystals to 4.5x2 cm. with silky luster, partly flattened by contact, on a bed of muscovite. At bottom the muscovite forms rosettes of hexagonal crystals to 0.8 cm. There are tiny globules of golden pyrite on the muscovite as well as a couple of small quartz crystals. Some bruising at the muscovite at bottom and a small cleaved area in the siderite. 6x5x2.2 - 15 € |

WPAN-13 - Siderite and quartz Barroca Grande Mine, Panasqueira, near Silvares (Fundao, Portugal) Group of creamy crystals of siderite to about 2.5 cm. attached to a partial translucent white quartz crystal recrystallized at back. There is an area with rosettes of hexagonal muscovite crystals to 4 mm. and a scattering of brassy microcrystals of probably marcasite on the siderite. The quartz presents a 3-mm. included black crystal of sphalerite. Siderite at back is contacted and the muscovite crystals present some bruising, otherwise undamaged. 7x5x3.5 - 20 € |

WPAN-14 - Ferberite and siderite Level 3, Barroca Grande Mine, Panasqueira, near Silvares (Fundao, Portugal) Cluster of silky-lustered creamy prismatic hexagonal crystals of siderite to about 0.5 cm. across with a black composite 3.1x2.3x0.8-cm. crystal of ferberite attached at back. Sandwiched in between there are some lustrous almost colorless crystals of apatite and the whole is partly coated by 1-mm. white rhombs of calcite. Just at center one siderite crystal is cleaved, otherwise quite well. 3.2x3x2.5 - 12 € |

WPAN-5 - Arsenopyrite, marcasite and calcite Barroca Grande Mine, Panasqueira, near Silvares (Fundao, Portugal) A base of arsenopyrite crystals overgrown by a 1-mm. thin layer of brassy marcasite. There are tiny marcasite crystals here and there. Crossing the specimen there is a string of opaque white saddle-shaped crystals of calcite to 1 cm. Some bruising in a couple of calcite crystals. 5x4.5x1.8 - 15 € |

WPAN-7 - Arsenopyrite and muscovite Barroca Grande Mine, Panasqueira, near Silvares (Fundao, Portugal) Floater cluster of dull silvery striated crystals of arsenopyrite to 3 cm. intermixed with rosettes of hexagonal crystals of muscovite to 0.6 cm. At bottom there are a few 2-mm. lustrous golden crystals of marcasite. Some oxide staining as can be seen in the pictures. Some small nicks here and there. 5.5x4x3 - 15 € |

WPAN-SW/70 - Arsenopyrite, marcasite and pyrite Panasqueira, near Silvares (Fundao, Portugal) Heavy floater cluster of lustrous silvery striated crystals of arsenopyrite to 3.5x3 cm. epitaxialy overgrown by brassy marcasite crystals. The marcasite itself is also epitaxialy coated by a layer of oriented cubic 1-mm. pyrite crystals. A few small creamy crystals of siderite. Bottom is contacted and partly recrystallized. One crystal is partly missing, the main ones are undamaged. Very interesting old specimen. 6.5x5x4 - 55 € |
