2 1 Podzolic brown forest soil, C-horizon. Leucophyllite. In the thin section mosaic quartz fields and bundles of leuchtenbergit could be observed as main components. 2 Acidic, non-podzolic brown forest soil, C-horizon. Phyllite. As main components bundles of mica-like minerals and mosaic pattern quartz fields were observed in thin section. Sometimes limonites mottles could be found in micaceous fields.
