Mineral assemblages, comositional variation, and crystal structure of feruvitic tourmaline from a contaminated anatectic pegmatite at Mirošov near Strážek, Moldanubian Zone, Czech Republic

Original language description

Amphibole-bearing, simply zoned, anatectic pegmatite, up to 20 cm thick, cuts calc-silicate rocks at Mirogov, near Strazek, in the Moldanubian Zone of the Czech Republic. Common amphibole (K-rich magnesio-hornblende to ferro-hastingsite), plagioclase An(30-42) and titanite, along with accessory feruvitic tourmaline-Ca-rich schorl to Na-rich feruvite-are indicators of Ca and Fe-contamination from the host rock. Interstitial tourmaline from the outer unit (TU1) and tourmaline from graphic intergrowths with quartz in more evolved parts of the pegmatite (TU2) have similar chemical compositions (EMPA, LA-ICP-MS) with Ca = 0.37-0.58 apfu, Al = 4.77-5.77 apfu; TU1 has higher Mg/(Mg + Fe-tot) = 0.52-0.41 compared to TU2 (0.39-0.15). TU1 is enriched in Ti, V, Cr, Sr, and TU2 in Li and Zn, respectively. Late microscopic veinlets of Na,Al,Mg-enriched tourmaline (TU3)-Ca-rich dravite/schorl-replace both TU1 and TU2.
