Abstract:

Detrital cohesive deposits belong to the most common present-day sediments known from various terrestrial environments, some shallow-marine ones as well as tidal flats. Lithologically, they include a very wide range of clastic materials varying in size from rudites (angular or rounded), through arenites, to lutaceous materials. Detrital cohesive deposits constitute a variety of landforms from small anthills to extensive floodplain sheets or prominent clay dunes that accompany some coastal zones. To the most common lithologie variétés belong clay rubble, clay gravel (pebbles, balls), soil pebbles (sand) clay sand (clayarenite) soil sand (soilarenite) and soil mud (soillutite). Genetically, the deposits may be classified as autoclastic, hydroclastic, anemoclastic, bioclastic or hybrid. All transitions may be encountered from pure cohesive deposits, through mixed ones, to ordinary (epi)clastic materials. Mixed deposits (e.g. the majority of intraformational conglomerates) have perhaps the best chance to be preserved in a fossil record and have been reported since the Late Pre-Cambrian till the Holocene.
