Description
Rare Fluornatromicrolite (type locality) with Muscovite, Albite, and Schorl, Lavra Quixaba, Frei Martinho, Paraiba, Brazil, cabinet, 7.0 x 5.0 x 4.5 cm, Well-formed, green-brown, octahedral crystals of fluornatromicrolite to 4mm in a granite pegmatite matrix consisting of silvery, equigranular muscovite, fleshy albite, and small, black, striated schorl crystals. Although labeled as "bismutomicrolite", the Microlite Group mineral at the Quixaba pegmatite was determined to be fluornatromicrolite as described in 1998, but not published until 2011 due to the revised nomenclature of the Microlite Group and Pyrochlore Supergroup. This specimen is from the type locality. Ex. Paulo Matioli collection.
