Anotace
Anchimetamorphosed sandstones and conglomerates of the so-called “Basal De vo nian Clastics”, that build a hill (ridge) named Babí lom, are considered to be of Lower to Middle Devonian age. Al though they are strongly tectonically affected, many sedimentary features are well-preserved and distinct. Both the facies and structures typical of alluvial fans and rivers were recognized in the sedimentary association at Babí lom. Among others, there are channel lags with imbricated grains, cross-bedding, and debrites. The way-up direction is clearly seen via repetitive coarsening-upwards sequences. Assuming a lack of rotation of the succession in the X–Y plane, the main palaeodrainage was towards the north and the major supply of material was from the east. The high maturity of the rocks suggests derivation from older deposits and/or highly weathered source rocks. The magmatic rocks of the Brunovistulicum are possibly the primary source of the sediments.
