“…Strong tidal currents and tidal dominance for the Puerto Madryn Formation is clearly expressed in the coarsegrained lag deposits flooring the channels, the abundant scour surfaces, the presence of large subaqueous dunes and upperflow regime sedimentary structures (Scasso et al 2015a, their Figs. 28 to 32;compare with Flemming and Davies 1994, and with the axial deposits of Dalrymple et al 2012) as well as in widespread tidal rhythmites, which are typical of macro-to hypertidal systems (Archer 1995(Archer , 2013Tessier 2012;Archer and Greb 2012). On the other hand, a macrotidal regime is still present in the Península Valdés region and it must have been similar in the late Miocene because only negligible changes in latitude or shelf width took place.…”

“…The rhythmites mostly lack marine fossils and bioturbation is rare, suggesting deposition under stressing environmental conditions, which is consistent with brackish waters and high sedimentation rates with high suspended sediment concentrations and minimal bioturbation and wave reworking (e.g., Thomas et al 1987;Tessier and Gigot 1989;Dalrymple et al 1991). The rhythmites are regarded as typical of macrotidal to hypertidal settings (Archer 1995;Tessier 2012), and they are better developed with extreme tidal dynamics within transgressive systems (Archer and Greb 2012).…”

“…On the other hand, high sedimentation rates and rapid aggradation in tidal channels within macro-to hypertidal areas promote the abundance of tidal rhythmites under transgressive conditions (Archer and Greb 2012;Archer 2013). Aggradational conditions are dominant during volcanic eruptive periods (Smith 1991), and may lead to the instantaneous preservation of channel geometry in transitional settings (Cuitiño and Scasso 2013).…”

The late Miocene beds of the Puerto Madryn Formation (Provincia del Chubut, Argentina) are formed by shallow marine and estuarine sediments. The latter include several tidal-channel infills well exposed on the cliffy coast of the Peninsula Valdés. The Bahía Punta Fósil and Cerro Olazábal paleochannels are end members of these tidal channels and show a fining-upward infilling starting with intraformational channel lag conglomerates above deeply erosional surfaces interpreted as fluvial ravinement surfaces (the erosion surface formed in the purely fluvial or the fluvially dominated part of the estuary, where erosion is driven by fluvial processes). These are overlain and eventually truncated (and suppressed) by the tidal ravinement surface (TRS), in turn covered with high-energy, bioclastic conglomerates mostly formed in the Btidally dominated/fluvially influenced^part of an estuary. Above, large straight or arcuate point bars with alternatively sandy/muddy seasonal beds and varying trace and body fossil contents were deposited from the freshwater fluvially dominated to saline-water tidally dominated part of the estuary. The upper channel infill is formed by cross-bedded sands with mud drapes and seaward-directed paleocurrents, together with barren, volcaniclastic sandy to muddy heterolithic seasonal rhythmites, both deposited in the fluvially dominated part of the estuary. Volcanic ash driven by the rivers after large explosive volcanic eruptions on land resulted in sedimentation rates as high as 0.9 m per year, preserving (through burial) the morphology of tidal channels and TRSs. The channel deposits were formed in a tide-dominated, macrotidal to hypertidal open estuary with welldeveloped TRSs resulting from strong tidal currents deeply scouring into the transgressive filling of the channels and eventually cutting the fluvial ravinement surface. The TRSs extended upstream to the inner part of the estuary during long periods of low sedimentation rates, extended channel migration and sediment bypass, interrupted by transient, high volcaniclastic input. The tidal channels of the Puerto Madryn Formation constitute a unique example of estuary sedimentation with pulsed sediment supply in a macrotidal to hypertidal estuary.

“…Tidal rhythmites have been reported from estuarine facies in the Kanawha Formation from nearby Boone County (Greb and Martino, 2009;Martino, 1996). Factors that favored tidalite development during the Pennsylvanian included 1) high frequency glacioeustatic sea level changes with widespread development of incised valley-fills, 2) coastal embayments that enhanced tidal resonance, and 3) high accommodation space produced by compacting peats or deep scours from channel avulsion (Archer and Greb, 2012). 5.6.…”

Recognition of Tidal-Bore Deposits In the Rock Record: Towards A Facies Model

A facies model for the deposits of tidal bores (upstream-propagating hydraulic jumps associated with the flood tide in estuarine rivers) has not yet been developed, despite the publication of data from laboratory experiments and some modern estuaries. Moreover, only one example of tidal-bore deposits has hitherto been identified in the rock record. Herein, we document evidence for tidal bores in an Upper Pennsylvanian (Virgilian, Gzhelian) incised-valley fill in northeastern Kansas, USA. Across the flanks and crest of a bank-attached bar remnant in this fill are thin (, 10 cm) lenses of muddy, massive sandstone and massive, plant-debris-rich sandstone bounded by erosion surfaces exhibiting symmetrical wave ripples and irregular scouring. This interval is enclosed by sandstones with bidirectional cross-stratification, rhythmites, mud drapes, flaser bedding, and related sedimentary structures that together record appreciable tidal influence. The erosion surfaces bounding the massive sandstone lenses, and the massive sandstone lenses themselves, are evidence for scour and sediment suspension by upstream-propagating bores followed by deposition from suspension after their passage. Not only are these deposits the first sedimentary record of tidal bores to be documented in the Pennsylvanian of the USA, they are only the second example of such deposits to be documented in the global rock record. On the basis of our observations, we propose a provisional facies model for tidal-bore deposits that can be refined by future work.
