Abstract

[Highlights

  • Sandstones were sampled on the Cretaceous divergent margin of the Demerara Plateau (Buteur Ridge)
  • Sedimentary and thermal history evidences two‐rifting stage of the Equatorial Atlantic
  • The onset of the first rift stage of the Equatorial Atlantic rift occurred during the Hauterivian
  • The second rift stage began during the Cenomanian and likely ended during the Late Cenomanian

, ABSTRACT

The permanent oceanic connection between the Jurassic Central Atlantic and the Cretaceous South Atlantic was only established with the late opening of the Equatorial Atlantic, but the timing of this event remained unclear due to a lack of geological dating. In 2023, the DIADEM oceanographic cruise conducted sampling of the Buteur Ridge, offshore French Guiana, by dredging and during a manned deep submersible () dive. The Buteur Ridge belongs to the eastern rifted margin of the Demerara Plateau, formed during the Lower Cretaceous Equatorial Atlantic rift. It is a 7 km‐long and 6 km‐wide tilted block, located at a depth of 3750 m, where sedimentary records of the Equatorial Atlantic are outcropping, making it an ideal location for investigating the timing of this rift.

We integrate petrological observations, biostratigraphy, fission‐track analyses of detrital apatites and zircons, and LA‐ICP‐MS U–Pb dating of authigenic apatites to reconstruct the sedimentary, diagenetic and thermal history of the sediments sampled on the Buteur Ridge.

Our results constrain the tectono‐sedimentary evolution of the divergent margin of the Demerara Plateau, revealing a complex rifting history of the Equatorial Atlantic involving two distinct rifts. The onset of the first rift occurred between 130 and 125 Ma (Hauterivian), which is earlier than the previously proposed Aptian age. A second rifting then occurred during the Cenomanian, likely during the kinematic reorganisation between Africa and South America in the Equatorial Atlantic. This later rifting is evidenced on the Buteur Ridge by terrigenous sedimentation followed by telodiagenesis during basin inversion, likely related to normal fault reactivation and ridge uplift. We interpret the crystallisation of authigenic apatites, dated 93 ± 12 Ma, as a record of the subsequent onset of marine transgression at the end of this second rifting, likely not occurring after the Late Cenomanian (circa 93 Ma).

,

Reconstructing the sedimentary, diagenetic, and thermal history of sediments from the Buteur Ridge (tilted block) constrains the evolution of the Demerara Plateau's Cretaceous divergent margin. The results reveal two distinct rifts of the Equatorial Atlantic, the first one starting during Hauterivian, a second rifting occurring during Cenomanian, the latter likely linked to the kinematic reorganisation between Africa and South America.
