From the belt of Ordovician metapelites in the Železné hory Mountains, ottrélite was described in 1882. Material newly collected in the vicinity of the Bučina Hill (606 m a.s.l.) SW from the Vápenný Podol village fits the original description, i.e. felsic rocks rich in quartz and illite-muscovite, with significant schistosity and abundant porphyroblasts of a dark green mineral of the chloritoid group up to 3 mm large. WDS analysis resulted in (Fe0.83Mg0.17Mn0.01)Σ1.01Al1.97(SiO4)Σ1.02O0.92(OH)2.00, i.e. chloritoid. Among the accessory minerals in the schist, possibly primary grains of xenotime-(Y) and more common rhabdophane-(Ce) in form of acicular, partly skeletal crystals in cavities, possibly after leached apatite were noticed.
We suggest using the term “chloritoid schist” for these metapelites formed at the contact of Middle to Late Ordovician graphite shales with the intrusion of the Variscan biotite granite of the Železné Hory Mts. Plutonic Complex.
