Description
| - Oxy-schorl, Na(Fe2+2Al)Al6Si6O18(BO3)3(OH)3O, is a new mineral species of the tourmaline group and it was found on two localities – Přibyslavice, Czech Republic and co-type locality Zlatá Idka, Slovak Republic. Oxy-schorl from Přibyslavice occurs in a foliated muscovite-tourmaline orthogneiss with associated minerals including K-feldspar (orthoclase-perthite), albite, quartz, muscovite, biotite, apatite and garnet. Oxy-schorl from Zlatá Idka occurs in extensively metasomatically altered Silurian metarhyolite pyroclastics with muscovite, quartz, and albite. Oxy-schorl from Přibyslavice forms abundant brownish black subhedral, columnar crystals, up to 1 cm in size, arranged in thin layers, or irregular clusters up to 5 cm in diameter in muscovite-tourmaline orthogneiss. Oxy-schorl from Zlatá Idka forms fan-shaped aggregates of greenish black acicular crystals ranging up to 2 cm in size, with aggregates up to 3.5 cm across. Oxy-schorl has a brown (Přibyslavice) to pale grey (Zlatá Idka) streak. Oxy-schorl from both localities is brittle and has a Mohs hardness of ca 7. It has no observable cleavage and parting. Oxy-schorl has a measured density of 3.19 g/cm (Přibyslavice) and 3.17 g/cm (Zlatá Idka) using pycnometry and calculated density of 3.198 g/cm (Přibyslavice), 3.208 g/cm (Zlatá Idka) using empirical formulae and separate unit cell data. In plane polarized light, it is pleochroic, O = dark greyish-green (Přibyslavice) and green to bluish-green (Zlatá Idka), E = pale brown (Přibyslavice) and pale yellowish to nearly colorless (Zlatá Idka). Oxy-schorl is uniaxial negative. Oxy-schorl is trigonal, space group R3m, a = 15.9853(12) Å, c = 7.1538(6) Å, V = 1583.1(2) Å3, Z = 3.
