Unidirectional solidification textures and garnet layering inY enriched garnet bearing aplite pegmatites in the CadomianBrno Batholith, Czech Republic

Original language description

Layered, garnet bearing aplite pegmatite dykes of the Hlína granitic suite, ~2 to 50 m thick and up to ~200 m long with general NW SE orientation and dip 40 80 to NE or SW, cut granodiorites to granites at the SW part of the Brno Batholith, Brunovistulicum, Czech Republic. Aplite pegmatite bodies are characterized by alternation of two main textural units: (i) fine grained aplite unit with garnet stripes and (ii) coarse grained pegmatite unit with oriented Qtz, Plg and Kfs comb like crystals known as Unidirectional Solidification Textures (UST). Both units developed in zones with the thickness varying from several cm to ~1 2 m for aplite unit, and ~10 cm for the UST unit. All rock types are characterized by high contents of SiO2 (74.6 75.7 wt. %), K2O(4.61 4.94 wt. %), Na2O (3.82 4.21 wt. %), moderate concentration of CaO (0.94 1.11 wt. %), and low to very low concentrations of Fe2O3 T (0.62 0.93 wt. %), MgO (0.0 0.03 wt. %), and TiO2 ( 0.03 wt. %).
