Non-seagrass meadow sedimentary facies of the Pontinian Islands, Tyrrhenian Sea: A modern example of mixed carbonate–siliciclastic sedimentation

Depositional architecture and sequence stratigraphy of the Oligo–Miocene Asmari platform; Southeastern Izeh Zone, Zagros Basin, Iran

“…The inner part of this carbonate ramp, like in the large Nummulites-dominated homoclinal ramp, is located in the Yasuj (Vazag), whereas the mid-and outer-ramp are located in the Eshgar and Anneh areas. The inner-ramp deposits consist of FA-V and FA-VI characterized by high-diversity benthic foraminiferal assemblages (seagrass community), developed in euphotic conditions, at shallow depths (Chaproniere 1975;Beavington-Penney et al 2006;Brandano and Civitelli 2007;Mateu-Vicens et al 2008;Zamagni et al 2008;Brandano et al 2009bBrandano et al , 2010Riordan et al 2012). Basinward, as light decreased, a "sandy" seafloor developed in the mid-ramp area (mesophotic conditions), in which the most prolific carbonate producers were the large nummulitids and lepidocyclinids (FA-III).…”

Paleoecology and dynamics of coralline dominated facies during a Pleistocene transgressive–regressive cycle (Capo Colonna marine terrace, Southern Italy)

“…Posidonia meadows are also known to generate mud rich skeletal packstone (Pomar, 2001;Fornos and Ahr, 2006) similar to the bed in which the pralines were collected. It is therefore possible that the lower interval of the rhodolith bearing packstone records a spatially complex environment at the interface between Posidonia meadows and slightly deeper red algae dominated bottoms (Carannante et al, 1988;Canals and Ballesteros, 1997;Fornos and Ahr, 2006;Brandano and Civitelli, 2007).…”

Depositional model and paleodepth reconstruction of a coral-rich, mixed siliciclastic-carbonate system: the Burdigalian of Capo Testa (northern Sardinia, Italy)

“…Mixed depositional systems have recently received increased attention in the geologic literature, first via the study of photozoan systems (Doyle and Roberts 1988;Piller and Mansour 1994;Testa and Bosence 1998;Ferro et al 1999;Dunbar et al 2000) and, more recently, examining heterozoan systems (Gillespie and Nelson 1997;Read 2004, 2007;Halfar et al 2004;Brandano and Civitelli 2007). In the fossil record (Hayward 1982;Santisteban and Taberner 1988;Wilson and Lokier 2002;Sanders and BaronSzabo 2005;Wilson 2005;Lokier et al 2009), but also at the present time (Woolfe and Larcombe 1999;Perry 2005), it is quite common to find coral reefs that are physically related to terrigenous sediments.…”
