The post-meeting field trip


Szklary Pegmatite


The Szklary pegmatite occurs within the Szklary serpentinite massif famous for the gem quality chrysoprase. List of minerals in the pegmatite comprises over 60 species, including: schorl, spessartine, chrysoberyl, beusite, columbite-(Fe), columbite-(Mn), tantalite-(Mn), stibiocolumbite, stibiotantalite, holtite, As- and Sb-bearing dumortierite, pyrochlore-supergroup minerals, pollucite,  purpurite. The Szklary pegmatite is the type locality for nioboholtite, titanoholtite and szklaryite.

The phosphates-rich Michałkowa pegmatiteoccurs within gneisses and amphibolites of the Sowie Mtns. block. More than 30 species have been described from the pegmatite, including allaudite, columbite-(Fe), cordierite, ferrisicklerite, graftonite, heterosite, hureaulite, schorl, vivianite. It is sarcopside type locality.

Piława Górna Pegmatite

The mixed  NYF/LCT Julianna pegmatitic system from the Piława Górna quarry discovered in 2008 occurs as a network of dikes in amphibolites, eclogites and migmatites of the Góry Sowie Block. More than 100 species have been found so far, including schorl, almandine-spessartine series, spodumene, olenite, elbaite, liddicoatite, lepidolite, beryl, pezzotaite, pollucite, lithiophilite, columbite-tantalite group. Piława Górna is type-locality for pilawite-(Y).


Strzegom Pegmatites

 Famous miarolitic cavities (NYF) in the Variscan post-tectonic Strzegom granite. More than 90 species have been described from the cavities, including fine specimens of smoky quartz, amazonite, fluorite, epidote, stilbite, chabasite, topaz, bavenite, beryl, phenakite, milarite, masutomilite, columbite-tantalite group, stilpnomelane, and „local” variety of Fe-chlorite named „strigovite” after the latin name of the town.
