摘要

在捷克外西喀尔巴阡山脉Magura Flysch ra a单元Zlín组始新统至渐新统砾岩中发现的绿绿片岩砾石的新产状，是这一贡献的特征。岩石的矿物组成非常简单，包括绿泥石、石英、白云母和微量磷灰石、金红石和独居石。类氯酸盐只含有极少量的镁类氯酸盐(7 - 11mol . %)和硅酸盐(高达0.4 mol. %)成分。白云母的组成与白云母和伊利石相对应。在与捷克共和国、斯洛伐克和奥地利潜在源区的类似岩石类型进行比较时，岩石矿物组合以及类绿石和白云母的化学成分通常出现显著差异。在捷克Silesicum Hrubý Jeseník Mts. bricl的类氯片岩中，化学成分的最佳可比性仅为类氯片岩。

Příspěvek k poznání exotických hornin flyšového pásma Západních Karpat: chloritoidová břidlice z Nového dvora u Kvasic (Chřiby)

New occurrence of pebbles of chloritoid schists, found in Eocene-to-Oligocene conglomerates of the Zlín Formation, Rača Unit, Magura Flysch, Outer Western Carpathians, Czech Republic, is characterized in this contribution. The rock has very simple mineral composition, including chloritoid, quartz, white mica and trace amount of apatite, rutile, and monazite. Chloritoid contains only very small proportions of magnesiochloritoid (7 - 11 mol. %) and ottrelite (up to 0.4 mol. %) components. The composition of white mica corresponds to muscovite and illite. The significant differences in mineral assemblages of rocks as well as in chemical composition of chloritoid and white mica usually appeared during comparison with those of similar rock types occurring in potential source areas in the Czech Republic, Slovakia, and Austria. The best comparable chemical composition showed only chloritoid in chloritoid schist from Bělá in the Hrubý Jeseník Mts., Silesicum, Czech Republic.
