“…The extent and significance of mixed carbonatesiliciclastic sediments have been the topic of increased research efforts (e.g., Brooks et al, 2003b;Read, 2004, 2007;Halfar et al, 2004;McNeill et al, 2004;LaGesse and Read, 2006;Best et al, 2007;Francis et al, 2007;Harilal et al, 2008). Common depositional controls affecting mixed carbonate-siliciclastic systems include distance from siliciclastic sources, relative sea level change, and climate.…”

This study presents a lithology-based sequence-stratigraphic framework and depositional model for Lower Cretaceous, mixed siliciclastic-carbonate sediments of the Mid-Atlantic coastal plain (eastern United States). Lithologic data from cores and cuttings were integrated with wireline logs and twodimensional seismic data to document lithofacies variability and stacking patterns across the Albemarle Basin of eastern North Carolina. Ten facies associations are defined, which are variably present within siliciclastic-and carbonate-dominated depositional profiles interpreted to extend from onshore lowland coastal plain to deep-shelf depositional environments.Three depositional sequences (0, 1, 2) were identified, each with component upward-shoaling parasequences. Seismic reflectors typically coincided with key sequence-stratigraphic surfaces, which guided correlations between wells. Parasequences are grouped into parasequence sets with progressive progradational or retrogradational (highstand and transgressive systems tracts, respectively) stacking patterns. Transgressive parasequences are thinner, uniform in thickness, and tend to be more dominated by molluskan carbonate facies. Highstand parasequences have more variable thickness, are siliciclastic dominated, and tend to be progradational on seismic data. Late highstand deposits of sequence 1 are dominated by restricted carbonate facies that likely reflect increased aridity. Lowstand deposits were not recognized from onshore well and seismic data.

“…The Castle Hayne Limestone (Ward et al 1978;Hazel et al 1984;Harris et al 1993;LaGesse & Read 2006;Coffey & Read 2007) is dominated by a bryozoan-echinoderm grainstone ⁄ packstone. This skeletal rich carbonate facies ranges in thickness from 2 to 15 m in outcrop and thickens to more than 200 m in the subsurface (Coffey & Read 2007).…”

Schimmel, M., Kowalewski, M. & Coffey, BP. 2011: Traces of predation/parasitism recorded in Eocene brachiopods from the Castle Hayne Limestone, North Carolina, USA. Lethaia, Vol. 45, pp. 274–289. The Castle Hayne Limestone (Middle Eocene, North Carolina), noted for its diverse macro‐invertebrate fossils, was sampled to assess if Early Cenozoic brachiopods from eastern North America record any traces of biotic interactions. Systematic surveys of two North Carolina quarries yielded 494 brachiopods dominated by one species: Plicatoria wilmingtonensis (Lyell and Sowerby, 1845). Despite subtle variations in taphonomy, taxonomy and drilling patterns, the two sampled quarries are remarkably similar in terms of quantitative and qualitative palaeoecological and taphonomic patterns. In both quarries, brachiopods contain frequent drillholes (24.5% specimens drilled). The majority of drillholes were singular, perpendicular to shell surface and drilled from the outside. Ventral valves were drilled slightly more frequently than dorsal ones, but site‐selectivity in drilhole location was not evident. Larger brachiopods were drilled significantly more frequently than smaller ones. However, drillhole diameter did not correlate with brachiopod size. The drillholes are interpreted as records of ‘live‐live’ biotic interactions, representing either predatory attacks or parasitic infestations or a combination of those two types of interactions. A notable fraction of specimens bear multiple drillholes, which is consistent with either parasitic nature of interactions or frequent failed predatory events. The high drilling frequency reported here reinforces other reports (from other continents and other epochs of the Cenozoic), which suggest that brachiopods may be an important prey or host of drilling organisms in some settings. The number of case studies reporting high frequencies of drilling in brachiopods is still limited and thus insufficient to draw reliable generalizations regarding the causes and consequences of these occasionally intense ecological interactions. □Brachiopods, drilling parasitism, drilling predation, Eocene, North Carolina, taphonomy.

“…Although terrigenous material can have detrimental effects on carbonate production, nevertheless, coeval deposition of siliciclastic and carbonate sediment can still occur in various depositional environments, such as continental shelf to slope (Coffey & Read, ; Francis, Dunbar, Dickens, Sutherland, & Droxler, ; Komatsu et al, ), carbonate platform (Cózar, Somerville, Rodríguez, Mas, & Medina‐Varea, ), lagoon (Isaack et al, ), tectonically active margin of basin (Chiarella, Longhitano, & Muto, ; Dorsey & Kidwell, ), and even foreland basin (Parcell & Williams, ; Reis & Suss, ). A complex combination of controlling factors often results in the coexistence of laterally juxtaposed and/or stacked carbonate and siliciclastic deposits whose lateral distributions and stacking patterns were controlled by eustasy, tectonics, climate change, in situ carbonate production, variations in siliciclastic influx, and paleotopography (e.g., Bastos et al, ; Chiarella & Longhitano, ; Chiarella, Longhitano, Sabato, & Tropeano, ; Chiarella, Longhitano, & Tropeano, ; Dix, Nehza, & Okon, ; Harper et al, ; LaGesse & Read, ; Lee & Chough, ; Navarrete, Rodríguez‐López, Liesa, Soria, & de Mesquita Veloso, ; Tcherepanov et al, ; Tucker, ). Two essential types of mixed sediments have been widely proposed, which can be classified as compositional mixing and strata mixing (Chiarella et al, ; Mount, ; Yang & Sha, ).…”

Mixed siliciclastic–carbonate sediments were well developed in the BZ‐X block as a subunit in the Huanghekou Sag in the southeastern part of the Bohai Bay Basin (China) during the Member 1 of the Shahejie Formation. An integrated approach based on detailed microscopic observation and core descriptions was applied to characterize the lithofacies types, facies associations, and depositional environment of the mixed sediments system. A detailed sedimentary facies analysis suggests that various lithofacies types can be grouped into four facies associations: mixed bioclastic sandy beaches (FA1), mixed clastic bioclastic shoal (FA2), mixed sandy oolitic shoals (FA3), and mixed distal bioclastic sandy beaches (FA4). These facies associations are interpreted to be deposited in varying depositional environments ranging from foreshore to shoreface setting in a shallow lake setting. An interplay of the climate regime, nearshore carbonate productivity, and current activity was proved to control the lithofacies types, dispersion and depositional environment change of mixed sediments in different depositional phases. Meter‐scale mixed cycles were found in this shallow lake setting and their features seem to differ from the classical mixed sediment models. It is suggested that these particular cycles in the stratigraphic record might indicate a typical mark of mixed sediment system in shallow areas of the lacustrine basin.
