“…3). Sedimentologic and ichnologic information was integrated in a sequence stratigraphic framework as outlined by Catuneanu (2006) and incorporated into a regional depositional model for the Mulichinco Formation within the Neuquén Basin (Schwarz and Howell, 2005;Schwarz et al 2006;Schwarz, 2012;Schwarz et al 2016, Veiga andSchwarz, 2016) in order to provide an accurate delineation of parasequences. Field work has allowed for in situ characterization of trace fossil content and sedimentary facies of the units studied.…”

“…Transgressive offshore sandstones are located below the fair-weather wave base within a low-gradient open-marine setting (Swift and Parsons, 1999) subject to consistent, predominantly unidirectional currents (Tillman and Martinsen, 1987;Tillman, 1999) representing a progradational dunefield that developed as a response to the onset of a tidal-transport system (Veiga and Schwarz, 2016). In previously studied deposits, this results in clean, cross-bedded (trough) and cross stratified (tangential and tabular), fine-grained sandstone interpreted as 3-D and 2-D subaqueous sand dunes that overlie the transgressive skeletal sandstones, representing the base of the sand dune.…”

“…Shell richness in the deposits between the OSB and the inferred BSB in the Montagna Piana motif (Figs A, C, D, A, and A) has probably been favoured by overall relatively low net sedimentation rates during transgression, which led to an increase in bivalve communities (e.g. Schwarz et al ., ), as well as by a higher amalgamation of event beds with respect to the HST. In few instances, however, OSBs are not clearly identifiable within Facies A2 (Figs A and A).…”

Discrimination between wave‐ravinement surfaces and bedset boundaries in Pliocene shallow‐marine deposits, Crotone Basin, southern Italy: An integrated sedimentological, micropalaeontological and mineralogical approach

et al. 2017

The lower Pliocene Belvedere Formation, cropping out in the Crotone Basin, southern Italy, exhibits a metre-scale to decametre-scale shallow-marine cyclicity that shares features of both high-frequency sequences linked to shoreline shifts and controlled by minor relative sea-level and/or sediment supply changes, and sedimentological cycles unrelated to shoreline shifts. In order to better understand the high-frequency sequence stratigraphic framework of this succession, an integration of sedimentological, micropalaeontological (microforaminifera assemblages) and mineralogical (heavy mineral abundance) data is used. From a sedimentological/stratigraphic point of view, wave-ravinement surfaces bounding high-frequency sequences, and associated substrate-controlled ichnofacies, are prominent in outcrop and document environmental and water-depth changes, whereas bedset boundaries separating sedimentological cycles have a more subtle field appearance and are only associated with changes of environmental energy. Moreover, condensed deposits are present only above wave-ravinement surfaces, and the high-frequency sequences bounded by these surfaces have a thickness that is an order of magnitude greater than that of the bedsets. Micro-foraminifera assemblages may change, and the content of heavy minerals usually increases, across wave-ravinement surfaces, whereas both parameters do not change significantly across bedset\ud boundaries. The abundance of heavy minerals is systematically higher, with respect to the underlying and overlying deposits, in the condensed shell beds that overlie wave-ravinement surfaces. An integrated sedimentological, micropalaeontological and mineralogical approach represents a powerful tool to discriminate between wave-ravinement surfaces bounding high-frequency sequences and bedset boundaries, and in general to investigate at the intra high-frequency sequence scale. This integrated approach is expected to be very useful in the study of potentially all shallow-marine successions composed of small-scale cycles, in order to delineate a detailed sequence stratigraphic framework and understand the factors that controlled the cyclicity
