Depositional model and sedimentation controls of a complex hybrid carbonate–siliciclastic ramp (albian) – sw campos basin, brazil

HIGHLIGHTS

• What: Lay summary | This study investigates the interaction between carbonate and siliciclastic sediments in the Campos Basin SE Brazil during the Albian geological age as the South Atlantic Ocean was forming. The petrographic analysis focused on three groups of lithofacies: dolomitized hybrid sandstones (present at the base of well 1-OGX-6-RJS, 3041.00 - 3010.00 m), hybrid sandstones and carbonates. The work shows that high-frequency sea level variations also influenced the position of the shoals, causing them to shift towards the shoreline over time.
• Who: Francyne Bochi do Amarante and colleagues from . . .
