Palaeontological framework from Pirabas Formation (North Brazil) used as potential model for equatorial carbonate platform [PDF]

Marine Micropaleontology, 2020
Abstract The Pirabas Formation (early to middle Miocene) from the equatorial margin of North Brazil is characterized by a shallow-marine carbonate platform with high fossil diversity and abundant micro- and macrofossil remains. The Pirabas Formation represents a unique carbonate system along the Atlantic margin of South America that developed before ...

Palaeoenvironment of the Miocene Pirabas Formation mixed carbonate–siliciclastic deposits, Northern Brazil: Insights from skeletal assemblages

Marine and Petroleum Geology, 2022
The Bragantina Platform is an onshore basin of the Brazilian equatorial margin, including the Pirabas Formation, the youngest bioclastic-dominated formation in the area (early–middle Miocene), testifying to the final demise of carbonate factories along this margin area and the transition to a siliciclastic-dominated sedimentation. Although the greatest

New species of Hippopleurifera (Bryozoa, Cheilostomata) from the Miocene <br />Pirabas Formation, Pará state, Brazil

Zootaxa, 2015
The Pirabas Formation in Brazil has been studied for many years and a great diversity of animal groups (in particular fishes, molluscs and echinoderms) have been described from there, whereas the Bryozoa have scarcely been mentioned. New samples, collected specifically to focus on bryozoans, have shown that the diversity in this formation is higher ...

X-ray micro-computed tomography of burrow-related porosity and permeability in shallow-marine equatorial carbonates: A case study from the Miocene Pirabas Formation, Brazil

Marine and Petroleum Geology, 2021
Abstract The Miocene Pirabas Formation is of strategic importance for the hydrocarbon industry since it represents the onshore portion of larger offshore basins of Northern Brazil, including the Foz de Amazonas, the Para-Maranhao, Barreirinhas, Ceara, and the Potiguar basins of the equatorial margin of South America.
