“…The shape of dish structures may change depending on amount of pressure, movement velocity of pore water and the degree of consolidation. These structures in Lake Van deposits are very similar to presented in previous works (Lowe & LePiccolo 1974;Lowe 1975;Neuwerth et al, 2006). Dish and pillar structures may occur with seismic shakings (Plaziat & Ahmamou, 1998;Moretti et al, 1999).…”

“…Deformation structures exist in different levels of these shallow water deposits with the other sedimentary structures as cross-beds and wave ripples. Soft sediment deformation structures are classified differently according to morphologic properties or occurrence processes of the structure (Rossetti, 1999;Dramis & Blumetti, 2005;Neuwerth et al, 2006;Taşgın & Türkmen, 2009). In this study, soft sediment deformation structures, observed in lacustrine deposits of Lake Van, were classified as contorted structures (simple-complex convolute bedding and ball-pillow structures), load structures (flame structures) and water escape structures (dish and pillar structures).…”

A part of the Upper Oligocene sand-rich turbidite systems of the Central Carpathian Basin is represented by the Zuberec Formation. Sand/mud-mixed deposits of this formation are well exposed in the northern part of the basin, allowing us to interpret the turbidite succession as terminal lobe deposits of a submarine fan. This interpretation is based on the discrimination of three facies associations that are comparable to different components of distributive lobe deposits in deep-water fan systems. They correspond to the lobe off-axis, lobe fringe and lobe distal fringe depositional subenvironments, respectively. The inferences about the depositional paleoenvironment based on sedimentological observations are verified by statistical analyses. The bed-thickness frequency distributions and vertical organization of the facies associations show cyclic trends at different hierarchical levels that enable us to reconstruct architectural elements of a turbidite fan. First, small-scale trends correspond with shift in the lobe element centroid between successive elements. Differences in the distribution and frequency of sandstone bed thicknesses as well as differences in the shape of bed-thickness frequency distributions between individual facies associations reflect a gradual fining and thinning in a down-dip direction. Second, meso-scale trends are identified within lobes and they generally correspond to the significant periodicity identified by the time series analysis of the bed thicknesses. The meso-scale trends demonstrate shifts in the position of the lobe centroid within the lobe system. Both types of trends have a character of a compensational stacking pattern and could be linked to autogenic pro-*Corresponding Author: Dušan Starek: Earth Science Institute SAS, Geological Division, Dúbravská cesta 9, 842 36 Bratislava; Email: dusan.starek@savba.sk Tomáš Fuksi: Earth Science Institute SAS, Geological Division, Dúbravská cesta 9, 842 36 Bratislava cesses. Third, a largescale trend documented by generally thickening-upward stacking pattern of beds, accompanied by a general increase of the sandstones/mudstones ratio and by a gradual change of percentage of individual facies, could be comparable to lobe-system scale. This trend probably indicates a gradual basinward progradation of lobe system controlled by allogenic processes related to tectonic activity of sources and sea-level fluctuations.

Synsedimentary de for ma tion struc tures have been rec og nized in Tri as sic and Cre ta ceous sed i men tary rocks of the Trutnov Ba sin, which build a struc tural and mor pho log i cal el e va tion be tween Èervený Kostelec and Upice.

Their shapes and spa tial dis tri bu tion strongly cor re spond to lo cal tec tonic struc tures within the Intrasudetic Shear Zone (ISZ), es pe cially to the faults which bound the rhomb-shaped de pres sions and el e va tions. All these struc tural sub-units com pose the Intrasudetic Ba sin Suite (IBS).
