WPOR-02/3 - Apatite and albite

Malpartida (Guarda District, Portugal)

A matrixless cluster of white bladed albite crystals to about 1 cm. across. Some crystals are epitaxially intergrown with creamy microcline. One side of the specimen is 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. Many of them show slightly hollow pinacoidal faces with the central area coated by fine-grained clay. Others have an interesting orange nucleus that quite probably is small included spessartine crystals. Apatite crystals are fluorescent in a salmon-pink color. There are some bits of smoky quartz and small 1-mm. orange spessartine crystals here and there. Some damage to the albite crystals. The light pink apatite aggregate seen in the picture below is partially contacted.

WPOR-02/5 - Apatite, quartz and albite

Malpartida (Guarda District, Portugal)

A matrixless plate of white bladed albite crystals to about 1 cm. across on both sides. Some crystals are epitaxially intergrown with creamy microcline. One side of the specimen is coated by a mixture of greenish clay and fine-grained muscovite while the opposite presents aggregates of muscovite rosettes and some lustrous transparent terminated crystals of dark smoky quartz to 0.8 cm. long. There are numerous lustrous colorless transparent crystals of apatite to 0.4 cm. across. A few show slightly hollow pinacoidal faces with the central area coated by fine-grained clay and a couple of them have an interesting orange nucleus that quite probably is small included spessartine crystals. Apatite crystals are fluorescent in a salmon-pink color. Some damage to the albite crystals.

WPOR-02/7 - Apatite, quartz and microcline

Malpartida (Guarda District, Portugal)

Matrixless plate of creamy microcline. On one side shows blocky crystals to about 0.5 cm. with aggregates of muscovite rosettes and some lustrous transparent terminated crystals of dark smoky quartz to 1.3 cm. long. The opposite side is coated by a mixture of greenish clay and fine-grained muscovite. On this side there are a few lustrous colorless transparent complex hexagonal crystals of apatite to 0.4 cm. across, fluorescent in a salmon-pink color. They show slightly hollow pinacoidal faces with the central area coated by fine-grained clay and a couple of them have an interesting orange nucleus that quite probably is small included spessartine crystals. Undamaged with the exception of a few non-terminated quartz crystals.

WPOR-02/8 - Apatite and quartz on albite

Malpartida (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.

WPOR-02/24 - Apatite on microcline

Malpartida (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.

WPOR-02/25 - Apatite, quartz and albite

Malpartida (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.

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.
