Lower Badenian deposits was newly outcropped on the locality Zaječí hora (Brno city). Sedimentological and paleontological study of the succession recognised two facies associations. The lower one was formed by the Lower Badenian clastic deposits known locally as „Brno sands“. The upper one is formed by the Lower Badenian offshore clays known as „Tegel“. The Neogene beds were covered by Quaternary loess loam. Lower Badenian succession is interpeted as progradation of the Gilbert-type delta foreset into relatively deep basin followed by the final flooding of the area by the open sea. The position of the locality close to a steep basin margins was prone to reflect role of local factors influencing the depositional processes and conditions.
