“…This migration resulted from the development of regional SE-and ESE-trending strike-slip fault zones and differently oriented normal fault sets (Knott and Turco, 1991;Tansi et al, 2007;Zecchin et al, 2015). From the Late Pliocene to Pleistocene, some parts of the back-arc zone were affected by extensional tectonic phase, WNW-ESE oriented, superimposed on strike-slip deformations, which resulted in the development of narrow transversal basins, such as the Catanzaro, Siderno and Messina straits, linking the Ionian Sea to the Tyrrhenian Sea with sublittoral sedimentation (Colella and D'Alessandro, 1988;Argnani and Trincardi, 1993;van Dijk et al, 2000;Chiarella et al, 2012aChiarella et al, , 2012bLonghitano, 2011;Longhitano et al, 2012;Longhitano et al, 2014;Chiarella, 2016) (Fig. 1B).…”

“…(i) Facies association 2Dcs consists of a rhythmic alternation of coarse-grained simple (facies Scs) and compound (facies Ccs) cross-strata sets. Facies Scs (Simple crossstrata) contains up to 5 m thick planar cross-strata sets with angular to tangential toeset geometry (Longhitano et al, 2014;Chiarella, 2016) (Fig. 4B).…”

Fault-controlled deposits develop in tectonically active basins forming tens of meters to hundreds of meters thick successions. Usually, the higher the syn-depositional cumulative displacement created by the fault, the thicker the deposit stacks (Hardy, Dart, & Waltham, 1994). Fault-controlled depositional systems have long been studied to improve the understanding and prediction of sand-and gravel-body architectures in analogous subsurface systems (Colella, 1988a;

“…The erosive (or reactivation) surfaces could also indicate periods of decreased sediment supply as well as the intermittent behaviour of the bottom current through time. The presence of tidal signatures, such as thickening and thinning foreset‐bundles (Allen, 1982; Longhitano & Nemec, 2005), gradual changes between angular to tangential toe‐set geometries ( sensu Chiarella, 2016), and foreset composition couplets (Ichaso & Dalrymple, 2009; Longhitano et al ., 2012) indicate that deposition took place in a tidally‐influenced environment. This suggests that the formation of the cross‐stratified beds took several tidal cycles (months to years), ruling out a turbiditic origin of these deposits.…”

Contourite channels – Facies model and channel evolution

Despite the rise in published evidence of deep-marine bottom current processes and associated deposits there are still very few documented outcrop examples. Herein are reported results of a contourite channel system related to the late Miocene palaeo-Mediterranean Outflow Water in the Rifian Corridor, Morocco. This work aims to unravel the sedimentary evolution and facies distribution based on the study of large morphological features related to contourite channels and their subsequent sandstone dominated infill sequences. It was found that the channel evolution and facies distribution are related to spatiotemporal changes in flow characteristics of the palaeo-Mediterranean Outflow Water. The recognized channel facies distribution correlates well with previously established bedform stability diagrams. Erosion and upper-stage flow regime bedforms are associated with the most vigorous bottom currents, generally related to its core. Laterally, following the decrease in flow velocity towards the adjacent drift, bedforms comprise dunes, lower-stage plane bedforms and more heterolithic facies. Similar facies changes are also observed down-channel, related to a decrease in flow velocities resulting from turbulent mixing of water masses, associated decreases in density gradients and the subsequent deceleration due to gravity. Results of this work have been used to propose a three-dimensional facies model for channelized sandy contourites. This study contributes to understanding contourite systems, thus benefitting oceanographic and climatic reconstructions as well as aiding the predictability of contourite channel systems for industry geoscience applications.
