- •
Diagenesis of Brazilian Equatorial Margin basins is poorly known.
- •
Diagenesis has a strong control on porosity of Equatorial Margin sandstones.
- •
Major processes in Pará-Maranhão sandstones: compaction, calcite & quartz cementation.
- •
Barreirinhas Basin sandstones diagenesis strongly controlled by primary composition.
- •
Compaction and dissolution control porosity in São Luís and Bragança-Viseu sandstones.
