Description An apparent contradiction between structural and sedimentological indications commonly used for discrimination of the overturned and non-overturned beds during geological mapping was found at Paršovice, a site situated in the easternmost part of the European Variscides. This outcrop of folded Lower Carboniferous siliciclastic rocks of the "Culm facies" lies on the NE margin of the Bohemian Massif, in the SE part of the Maleník Block (Moravia, Czech Republic). At the same site, a slump-related isoclinal fold was found. The apparent contradiction between structural (relation of cleavage and bedding) and sedimentological (flute casts on bed soles) indications is explained by a combination of successive phases of slump- and tectonically-related folding.
