Facies Analyses and Diagenetic Evolution of the Jandaíra Formation, Potiguar Basin

In this study was analysed thin sections and plugs from the facies of Jandaira Formation, a Turonian-Campanian carbonate platform in the Potiguar Basin. The focus was in samples from the Rosario outcrop and a few boreholes. Textural features, framework composition, diagenetic processes, and porosity types was determined. Were also measured petrophysical properties as permeability and porosity. With petrografic and petrophysical data we can produce a detail map to support structural and karst analyses in the study area.
