Expanding the spectrum of shallow-marine, mixed carbonate–siliciclastic systems: Processes, facies distribution and depositional controls of a siliciclastic-dominated example
(Wiley Blackwell Publishing, Inc, 2018-08)
Most of the present knowledge of shallow-marine, mixed carbonate–siliciclastic systems relies on examples from the carbonate-dominated end of the carbonate–siliciclastic spectrum. This contribution provides a detailed ...
Depositional controls on mixed carbonate-siliciclastic cycles and sequences on gently inclined shelf profiles
(Wiley Blackwell Publishing, Inc, 2015-12)
The interplay between carbonate production and siliciclastic input produces mixed systems that typically contain a very high degree of lateral and vertical facies heterogeneity. This heterogeneity complicates the sequence ...
Modern non-tropical mixed carbonate-siliciclastic sediments and environments of the southwestern Gulf of California, Mexico
(Sedimentary Geology, 2004)
Modern mixed carbonate-siliciclastic warm-temperate environments were studied in the southern Gulf of California (GOC), Mexico. The combined heterozoan and photozoan character is defined by the absence of true coral reef ...
3-d Geological Modelling: A Siliciclastic Reservoir Case Study From Campos Basin, Brazil
(Fundação Gorceix, 2016)
Petrographic, mineralogical and geochemical characterization of fine-grained rocks of the Pilmatué Member (Upper Valanginian-lower hauterivian) of the Neuquén Basin (Argentina): Implications for siliciclastic input, carbonate productivity and redox conditions
(Pergamon-Elsevier Science Ltd, 2020-10)
Petrographic, mineralogical and geochemical analyses of mixed siliciclastic-carbonate offshore deposits of the Pilmatué Member (Neuquén Basin) were carried out to define two scenarios for deposition: a confined ramp setting ...
Bioerosion and encrustation rates in recent mollusk death assemblages on a supratidal siliciclastic setting, Playa Norte, Veracruz State, Mexico
(Springer Verlag, 2018-04-26)
This study presents both qualitative and quantitative data regarding marine mollusk (gastropods and bivalves) shell bioerosion and encrustation based on death assemblages obtained from a recent supratidal environment in ...
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
(2018)
The Cretaceous black shales of Colombia are among the most important successions in the north of South America and have attracted the attention of many geoscientists and exploration companies over the last few decades, ...
Carbonate-siliciclastic sedimentation on a high-energy, oceanfacing, tropical ramp, NE Brazil
