Palaeoredox conditions and sequence stratigraphy of the Cretaceous storm-dominated, mixed siliciclastic-carbonate ramp in the Eastern Cordillera Basin (Colombia): Evidence from sedimentary geochemical proxies and facies analysis

A near-shore clastic-carbonate mixing mode in a continental rift basin (early Oligocene, eastern Shijiutuo Uplift, Bohai Bay Basin, China): sedimentology, reservoir characteristics and exploration practice

“…However no unified classification criteria have been accepted yet (e.g. Yang and Sha 1990;Zhang 2000;Brooks et al 2003;Coffey and Read 2004;García-Hidalgo et al 2007;Man 2014;Wang et al 2014;Chiarella et al 2017;Rivera et al 2018;Moscardelli et al 2019). In this investigation, we utilized a classification constituted by terrigenous clastics, biocarbonate grains and chemogenic carbonates as three components to reflect the original texture origins.…”

“…Researchers identified this special depositional phenomenon in different sedimentary environments including continental and marine setting and some achievements have been acquired (e.g. Mount 1984Mount , 1985Dorsey and Kidwell 1999;Brooks et al 2003;Coffey and Read 2004;Longhitano et al 2010;Morsilli et al 2012;Man 2014;Sarkar et al 2014;Chiarella et al 2017;Rivera et al 2018;Moscardelli et al 2019). Research processes of mixed sediments generally include i) the budding stage (before 1980s) (e.g.…”

“…Sanders and Pons 1999) and iv) comprehensive developing stage (early twenty-first century-present) (e.g. Brooks et al 2003;Coffey and Read 2004;García-Hidalgo et al 2007;Longhitano et al 2010;Mata and Bottjer 2011;Morsilli et al 2012;Man 2014;Chiarella et al 2017;Rivera et al 2018;Moscardelli et al 2019). Since the 1990s, detailed analyses have been made on mixed sediment in different areas in China (e.g.…”

“…Much more attention has been paid to the developing process of mixed sediment within a sequence stratigraphic framework (e.g. Brooks et al 2003;Coffey and Read 2004;García-Hidalgo et al 2007;Longhitano et al 2010;Morsilli et al 2012;Man 2014;Chiarella et al 2017;Rivera et al 2018;Moscardelli et al 2019). Furthermore, the study of sedimentary environments of mixed sediment is no longer restricted to marine or marinecontinental transitional facies, with attention being paid now to continental environments as well including backarc foreland basin (e.g.…”

“…However, the trace fossil assemblage still indicates a fully marine environment. These turbidite/tempestite events favoured the colonisation of opportunistic organisms, a mechanism that has proved to be effective to provide higher oxygenation and nutrients to an otherwise poorly oxygenated setting (Rivera et al, 2018). The Shcs and Spl facies suggest the influence of strong oscillatory or combined flows, whereas the associated symmetrical ripples (Sw) indicate the waning phases of storm-related events (Dott and Bourgeois, 1982).…”
