Mixed Siliciclastic-Skeletal Carbonate Facies on Wanganui Shelf, New Zealand: A Contribution to the Temperate Carbonate Model

Facies partitioning and sequence stratigraphy of cool-water, mixed carbonate-siliciclastic sediments (Upper Miocene Guadalquivir Domain, southern Spain)

“…As shown by Wilson (1988), Carey et al (1995), and Gillespie and Nelson (1997), carbonate production on the shelf is mainly during transgressive phases as, for example, during the youngest sea-level rise. This general pattern, however, is not valid in areas where sea-level fluctuations are accompanied by changes in humidity (Ferland and Roy 1997).…”

“…Examples of mixed, non-tropical carbonate siliciclastics are described from the British Isles (Wilson 1988;Scoffin 1988;Light and Wilson 1998), West Canada (Carey et al 1995), the Gulf of California (Foster et al 1997;Meldahl et al 1997), South Australia (James et al 1992Ferland and Roy 1997), Tasmania (Rao and Amini 1995), and New Zealand (Nelson et al 1988;Gillespie and Nelson 1997). In these papers it is shown that the facies composition is mainly controlled by water depth, morphology and topography of the basin, as well as the hydraulic regime.…”

“…In these papers it is shown that the facies composition is mainly controlled by water depth, morphology and topography of the basin, as well as the hydraulic regime. On open, mixed siliciclastic-carbonate shelves, high amounts of terrigenous material occur in two facies belts James et al 1992;Rao and Amini 1995;Ferland and Roy 1997;Gillespie and Nelson 1997;James et al 1997;Light and Wilson 1998). A shallow belt can be found in nearshore areas down to a water depth of approximately 40 m, and an outer belt appears in deeper slope and lower slope zones.…”

An integrated sequence stratigraphic, palaeoenvironmental, and chronostratigraphic analysis of the Tangahoe Formation, southern Taranaki coast, with implications for mid‐Pliocene (c. 3.4–3.0 Ma) glacio‐eustatic sea‐level changes

“…In its present and Holocene highstand state, the South Taranaki Bight continental shelf displays thin, patchy and isolated deposits of river borne, fine grained sediments overlying post-last glacial transgressive coastal deposits and relict/palimpsest carbonate sediments (Gillespie & Nelson 1997). Unlike the modern continental shelf, HST sediments in the Tangahoe Formation and other PliocenePleistocene Wanganui Basin sequences display thick (up to 30 m) aggradational intervals of bioturbated mudstone and fine sandy mudstone (e.g., Naish & Kamp 1997a).…”

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.…”
