“…Sinclair et al 1991;DeCelles et al 1998;Mutti et al 2003), this succession can be interpreted in terms of migrating depozones (see also Alavi, 2004 for the Zagros). In the Zagros, the wedge-top depozone is represented mainly by the Agha Jari and Bakhtyari formations, though in the Fars region, part of the Mishan also occupies a wedge-top position.…”

“…In doing so, we aim to place the various deposits observed within the context of foreland basin depozones (see also Alavi, 2004Alavi, , 2007, as already established for many other foreland basin systems (e.g. Sinclair et al 1991;DeCelles et al 1998;Mutti et al 2003). The Zagros system offers an advantage over many other foreland basins in that it is currently active and has been so for a considerable time period.…”

Neogene sediments and modern depositional environments of the Zagros foreland basin system

-A sedimentological investigation of the Neogene deposits of the Zagros foreland basin in SW Iran reveals a continuous and largely gradational passage from supratidal and sabkha sediments at the base (represented by the Gachsaran Formation) to carbonates and marine marls (Mishan Formation with basal Guri carbonate member) followed by coastal plain and meandering river deposits (Agha Jari Formation) and finally to braided river gravel sheets (Bakhtyari Formation). This vertical succession is interpreted to represent the southward migration of foreland basin depozones (from distal foredeep and foredeep to distal wedge-top and proximal wedge-top, respectively) as the Zagros fold-thrust belt migrated progressively southward towards the Arabian foreland. This vertical succession bears a striking similarity to modern depositional environments and sedimentary deposits observed in the Zagros region today, where one passes from mainly braided rivers in the Zagros Mountains to meandering rivers close to the coast, to shallow marine clastic sediments along the northern part of the Persian Gulf and finally to carbonate ramp and sabkha deposits along the southeastern coast of the Persian Gulf. This link between the Neogene succession and the modern-day depositional environments strongly suggests that the major Neogene formations of the Zagros foreland basin are strongly diachronous (as shown recently by others) and have active modern-day equivalents.

“…Riverine input of hyperconcentrated bedload during catastrophic floods that flow seaward due to inertia could generate voluminous flows (hyperpycnites) which deposited sandstone-siltstone beds [e.g. 67,[89][90][91] and could form hyperpycnal-fed turbidite lobe [e.g. 24].…”

“…Interpretation: The plane-parallel stratified sandstone could represent the deposit of a near-bed suspension generated by progressive turbulent mixing at the head of a sandy dense flow with relatively low rates of deceleration [67]. Each lamina can be considered to represent a traction carpet that is driven by basal shearing of an overlying turbulent flow.…”

Distal turbidite fan/lobe succession of the Late Oligocene Zuberec Fm. – architecture and hierarchy (Central Western Carpathians, Orava–Podhale basin)

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.

“…Of particular interest for the aims of this paper are the researches of Mutti and co-workers [26,27] and references therein. These authors subdivided shallow marine and shelfal foreland basin successions into three main types of depositional systems, based on their facies associations and relative water depth.…”

Partitioning between “wedge-top” river- and wave-dominated successions: an example from the late Tortonian — early Messinian Terravecchia Formation (NW Sicily)

Detailed field sedimentological and facies analyses have been performed in the Terravecchia Formation cropping out in NW Sicily, in order to differentiate and describe, for the first time, wave-and river-dominated shallow-marine (deltaic) siliciclastic successions. The latter were deposited filling syntectonic basins, developed between the late Tortonian and early Messinian time, within the wedge-top depozone of the Sicilian Foreland Basin System. It has been observed that river-dominated successions, recording the deposition of small fan-deltas are characterized by fining-to coarsening upward, transgressive-regressive sequences which were mostly deposited filling relatively narrow and often oversupplied basins. These basins were probably located in a proximal sector of the wedge-top depozone, closer to emergent sectors of the chain and probably sheltered from the main marine areas. Wavedominated successions, on the other hand, are characterized by upward fining, mostly transgressive sequences which were deposited filling wider basins open to major marine regions and located in a more distal position of the wedge-top depozone. The documented partitioning between river-and wave-dominated successions, as a function of the position of the sedimentary basin within the wedge-top depozone, is coherent with data from analyses of the deformational patterns of the Terravecchia Formation in this study area. Furthermore, the data here presented could be considered as a preliminary database for future characterization and analysis of siliciclastic reservoirs from Sicilian outcrop analogues.
