Garnet-bearing layered anorogenous granites and pegmatites of the Hlína Suite inside the Brunovistulicum – structures and field occurrences

The SW part of the Brno Batholith as well as NE part of the Thaya batholith have undergone recent mapping focused on layered granite dykes belong to the Hlína A-type granite suite. Dykes cropping out throughout the both other granitic suites in the region (Réna I-type and Tetčice S-type) widespread more than 60 km in N–S direction. Structures of the Hlína granites are easily distinguishable by their layering parallel to the contact, alternating of major aplite-like zones and minor pegmatite-like zones with oriented UST comb-like Qtz, Pland Kfs. The lamination of the rock is pronounced by parallel stripe-like arrangement of the garnet. The purpose of text below is highlighted the volumetrically scarce but genetically very important part of the Brunovistulian unit.The SW part of the Brno Batholith as well as NE part of the Thaya batholith have undergone recent mapping focused on layered granite dykes belong to the Hlína A-type granite suite.
