| Popis | Tourmalines (dravite-schorl-uvite-povondraite) from intragranitic pegmatites of the Třebíč Pluton (porphyric, amphibole-biotite melasyenite to quartz melasyenite-melagranite) were examined using electron microprobe, Mössbauer spectroscopy and laser ablation inductively coupled plasma mass spectroscopy (LA-ICP-MS). Black tourmaline occurs in several distinct morphological, paragenetic and textural types with very high variability in zoning; however, the morphological types of tourmaline do not differ in the chemical composition. Tourmalines generally show two trends distinct for the allanite-type and euxenite-type pegmatites and for the euxenite-type pegmatite Klučov I. |
