文摘
- •
The Potiguar Basin occurs in the Brazilian Equatorial margin.
- •
We investigate rift internal geometry and fault evolution in the Potiguar Basin.
- •
The fault geometry was derived from 3D gravity modeling, seismic and well data.
- •
Four main fault segments linked and formed the main rift border.
- •
Faults evolved from small segments and formed longer structures at a final stage.
