“…The most important tidal cycles observable in the rock record are fl ood-ebb (current period of 6-12 h), semi-diurnal (12.42 h), diurnal (24.8 h), tropical half-month (13.6 days), syzygy (14.76 days) and anomalistic month (27.5 days) (e.g. Visser 1980;Tessier & Gigot 1989;De Boer et al 1989;Nio & Yang 1991;Choi & Park 2000). Such cycles can be preserved in the sedimentary record either as cyclic thickness variation in heterolithic (e.g.…”

Marine infl uence in Amazonia during the Miocene is a controversial issue, one about which nearly opposite theories (continental vs marine) have been proposed. Increasing multidisciplinary palaeoenvironmental data sets from various Miocene stratigraphic levels and parts of Amazonia have revealed depositional complexities triggered by repeated, high-frequency base-level changes and a very low depositional gradient. As a result, Early-Middle Miocene strata (Pebas phase) are organized into recurring 3-10 m-thick transgressive-regressive bay-margin successions. An array of evidence indicates some sort of marine infl uence in these deposits. This evidence includes mangrove pollen, foraminifers, rare brackish-water mollusc species, barnacles, common brackish-water trace fossil assemblages and tidal sediments. The ongoing debate now focuses on the degree of saltwater infl uence in the Pebas phase strata. The Late Miocene (Acre phase) stratigraphic record comprises mainly channelized deposits, and fossil faunas are dominated by terrestrial and freshwater vertebrates. The evidence for marginal marine infl uence in these strata is mainly confi ned to inclined heterolithic stratifi cation (IHS)-bearing channels and includes tidal sediments, restricted brackish-water ichnofossil assemblages, and locally teeth of euryhaline sharks and mangrove pollen (Nauta and Madre de Dios Formations). In particular, the tidal signature in these deposits is well developed, pointing to local development of deltaic/estuarine settings. There are also suggestions of marine infl uence on other stratigraphic intervals throughout Amazonia, particularly in Pliocene and Quaternary strata. The allegedly marine conditions have been proposed based on purported global sea-level highstands, the low altitude of the Amazon region and supposed coastal geomorphological features such as deltas. We conclude that these suggestions are misconceptions and that geological data to support such marine settings during the Late Neogene are lacking.

“…Sedimentation during the early Ottnangian was mainly siliciclastic resulting in deposition of the characteristic sandy/ silty "Schlier" . Widespread tidalinfluenced deposits from Eggenburgian to early Ottnangian are reported from the area of the Burdigalian Seaway (Homewood & Allen 1981;Allen & Homewood 1984;Allen et al 1985;Faupl & Roetzel 1987Keller 1989;Tessier & Gigot 1989;Krenmayr 1991;Schaad et al 1992;Martel et al 1994;Salvermoser 1999;Bieg 2005).

Evidence for regional upwelling conditions in the Central Paratethys Sea is presented for mid-Burdigalian (early Ottnangian) times. The oceanographic phenomenon is detected in clay-diatomite successions along the steep escarpment of the Bohemian Massif in the eastern North Alpine Foreland Basin. Interpretations are based on a multiproxy data-set including published sedimentological and paleontological data, newly performed stable isotope measurements (δ 18 O, δ 13 C) of foraminifers and bulk sediment samples, and analyses of dinoflagellate cyst assemblages. The revealed stable isotope values of planktonic foraminifers point to upwelling: low δ 13 C values indicate strong mixing of surface waters with rising nutrient-rich waters, high δ18 O values reflect cool sea surface temperatures (SST). Temperature calculations give SSTs ranging from 10-14 °C. Cool SSTs and high productivity are additionally supported by bulk sediment analyses. Assemblages of dinoflagellate cysts indicate a distal-shelf environment with nutrient-rich waters. Westerly winds and tidal currents are discussed as potential driving forces behind the local upwelling event. As midBurdigalian geography favoured strong current patterns in the Central Paratethys as documented in the sedimentary record from the Rhône Basin to Hungary upwelling might have been a more common phenomenon in this epicontinental sea than currently known.

“…However, the most convincing evidence is the abundance of sedimentary structures diagnostic of tidal periodicities. This is particularly indicated in facies Sx by the laterally alternating thick-thin pairing marked by double mud couplets, which is similar to many others recorded in both modern and ancient tidal-generated deposits (e.g., Visser 1980, Allen 1981a, b, Boersma and Terwindt 1981, Nio et al 1983, Allen and Homewood 1984, Mowbray and Visser 1984, Tessier and Gigot 1989, Nio and Yang 1991, Archer et al 1995, Shanley et al 1992. Sandstones with lateral successions of tidal bundles are related to megaripple migration under fluctuating asymmetric flood and ebb tides.…”

Marine influence in the Barreiras Formation, State of Alagoas, northeastern Brazil

Tidal processes were important for deposition of the Barreiras Formation located in northern Brazil, while correlatable deposits in northeastern Brazil have been traditionally related to continental environments. Facies analysis in southern Alagoas revealed that the Barreiras Formation consists of cross-stratified conglomerates and sandstones (facies Sx and Cgx), compound cross-stratified sandstones (facies Cx), and heterolithic beddings (facies H). A significant portion of these deposits occurs within channel morphologies displaying fining and thinning upward successions. An abundance of sedimentary features is comparable to those from the northern Brazilian counterpart. These include: tidal bundles; herringbone cross-stratification; heterolithic beddings with sandstone and mudstone beds in sharp contacts; and ichnofossils mostly consisting of Ophiomorpha nodosa, Skolithos and Planolites. Altogether, these features point to a marginal marine depositional setting dominated by tidal processes, which are related to an estuarine system, an interpretation also provided for the Barreiras Formation in northern Brazil. The widespread occurrence of deposits with unambiguous evidence of tidal processes in the Barreiras Formation of northern Brazil, and now in the State of Alagoas, leads to argue that the early/middle Miocene worldwide marine transgression might have left a much more widespread sedimentary record along the Brazilian coast than currently regarded.
