WPAN-24 - Quartz, muscovite and calcite

Level 3, Barroca Grande Mine, Panasqueira, near Silvares (Fundao, Portugal)

Nice floater cluster of doubly terminated translucent white to colorless quartz crystals. At bottom there is an aggregate of hexagonal muscovite crystals to 1 cm. across. A few creamy prismatic hexagonal 1-cm. siderite crystals and some lustrous arsenopyrite crystals add to the whole. Back and bottom of the specimen are partly coated by a layer of 1-mm. white rhombs of calcite. Interestingly the termination of the main crystal has long gone and actually it is recrystallized. Some bruising at the muscovite crystals, otherwise undamaged.

WPAN-25 - Quartz, siderite, arsenopyrite and calcite

Barroca Grande Mine, Panasqueira, near Silvares (Fundao, Portugal)

A large opaque 11.5x5.5x4.5-cm. crystal of quartz with an attached cluster of creamy rhombic siderite crystals to 2.8 cm. across, lustrous arsenopyrite crystals to about 2 cm., a 1-cm. aggregate of chalcopyrite crystals, 1-mm. black globules of probably sphalerite and a partial coating of 2-mm. white rhombs of calcite. What is most important about this specimen is the richness in different inclusions in the quartz crystal. It is possible to appreciate complete crystals of silvery arsenopyrite and golden chalcopyrite to about 1 cm. across, skeletal and outlined crystals of arsenopyrite and probably ferberite to 2 cm. long, some golden crests of marcasite and layers of calcite. A real dream for the collector of included quartz. The termination of the quartz crystal is long gone and now there is one 1-mm. calcite rhomb crystallized on it. Some damage of little importance here and there, what is more interesting is the variety of inclusions.

WPAN-22 - Quartz, siderite and apatite

Level 3, Barroca Grande Mine, Panasqueira, near Silvares (Fundao, Portugal)

Group of singly terminated translucent quartz crystals partly coated by a layer of lenticular creamy siderite crystals to 3 mm. The siderite is also coated by sugary tiny white crystals of calcite. Below the siderite layer there are some partial crystals of lustrous green apatite. The apatite area presents some damage and is partly contacted.

WPAN-8 - Quartz and siderite

Level 3, Barroca Grande Mine, Panasqueira, near Silvares (Fundao, Portugal)

Floater cluster of transparent colorless quartz crystals almost completely coated by a layer of lenticular creamy siderite crystals to 3 mm. The siderite is also coated by sugary tiny white crystals of calcite. The quartz crystals are partly recrystallized as seen in the pictures but the specimen is undamaged.
