The Portugal Gallery includes a number of specimens from different localities in Portugal (excluding Panasqueira which has its own Gallery). Pages 1 to 3 are devoted to some pegmatites in central Portugal and show quartz, apatite, albite and others. |

WPOR-02/8 - Apatite and quartz on albite Portugal II Quarry, Malpartida, near Almeida (Guarda District, Portugal) Piece of pegmatite made of white albite, creamy microcline and greyish quartz. There is a vuggy area with crystallized albite on which several 2-mm. lustrous colorless transparent complex hexagonal apatite crystals rest. They are fluorescent in a salmon-pink color. Associated minerals are a lonely 0.4-cm. long smoky quartz crystal and tiny muscovite crystals. 4.5x4x3 - 9 € |

WPOR-02/24 - Apatite on microcline Portugal II Quarry, Malpartida, near Almeida (Guarda District, Portugal) Fragment of a large creamy microcline crystal with a coating of fine-grained greenish muscovite on most of the surface. In several areas, mainly at back, there are dozens of nice small colorless transparent complex hexagonal crystals of apatite to 0.4 cm. across. Apatites are fluorescent in a salmon-pink color. There are areas with small lustrous colorless albite crystals epitaxially overgrown on the microcline. With the exception of a relatively small broken area (seen at right in upper left picture), the specimen is a floater with no more damage. 11.2x9.2x3 - 50 € |

WPOR-02/25 - Apatite, quartz and albite Portugal II Quarry, Malpartida, near Almeida (Guarda District, Portugal) Large piece of pegmatite with a large crystal of creamy microcline (showing a twin plane at bottom) as a central core followed by a layer of white albite at the bottom half. Albite forms white bladed crystals to about 1 cm. across some of which are epitaxially intergrown with creamy microcline. Most of the specimen is then covered by dark smoky quartz crystals to about 3.5 cm. long, many of them naturally broken and showing an opaque white core with a rim of translucent almost black color. Large areas of the specimen are coated by a mixture of greenish clay and fine-grained muscovite. There are numerous lustrous colorless transparent crystals of apatite to 0.6 cm. across. A few have an interesting orange nucleus that quite probably is small included spessartine crystals. Apatite crystals are fluorescent in a salmon-pink color. The microcline crystal is broken and recrystallized at both ends, the specimen may be considered a floater. Some damage mostly in the quartz crystals but still an interesting pegmatitic specimen. 9.5x9x7 - 80 € |

WPOR-01/88 - Hureaulite Mesquitela, near Mangualde (Viseu District, Portugal) Pinkish vuggy masses of hurealulite in a quartz/phosphates pegmatitic matrix. There are some microcrystals inside the vugs. Sample has not been analysed and there may be other phosphates associated as well. 5.3x3.6x3.3 - 10 € |

WPOR-02/93 - Triplite and phosphosiderite Folgosinho, near Gouveia (Guarda District, Portugal) Mass of resinous brown triplite partly altered mainly to violet to purple vuggy phosphosiderite mixed with areas of microglobules of black nsutite. Sample has not been analysed and there may be other phosphates associated as well. 9x7.6x4.5 - 30 € |
