Orbital-driven cyclicity and the role of halokinesis on accommodation within siliciclastic to carbonate, shallow-water Albian deposits in the Espírito Santo Basin, southeastern Brazil

The basal section of the lower Albian Barra Nova Group in the onshore portion of the Regência Platform, a central-eastern geological province of the Espírito Santo Basin, Brazil, comprises a mixed succession characterized by the cyclic alternation of dominant fluvial to shallow marine, siliciclastic rocks and marine carbonate strata. Spectral analysis of gamma-ray logs of four wells has shown consistent evidence of a short eccentricity orbital...
