Transform marginal plateaus (TMPs) are large and flat structures commonly found in deep oceanic domains, but their origin and relationship to adjacent oceanic lithosphere remain poorly understood. This paper focuses on two conjugate TMPs, the Demerara Plateau off Suriname and French Guiana and the Guinea Plateau, located at the junction of the...
The Grenada back‐arc basin is located between the Aves Ridge, which hosted the remnant Early Paleogene "Great Caribbean Arc", and the Eocene to Present Lesser Antilles Arc. Several earlier studies have proposed different modes of back‐arc opening for this basin, including N‐S and E‐W directions. The main aim of this study is to constrain the...
Studying back-arc basins, where sedimentation is less deformed than in the forearc, provides complementary information about formation and tectonic evolution of subduction zones. At the Lesser Antilles subduction zone, the North and South American plates are subducting underneath the Caribbean plate at a velocity of 2 cm per year. The...
The Norfolk Ridge is a north-south trending ca. 1000 x 80 km bathymetric high located along the easternmost edge of the Zealandia continent at ca. 1 km water-depth. It lies in a key tectonic position which marks the boundary between Neogene subduction-related arcs and backarc basins to the east (e.g. 3-4 km deep Norfolk Basin) and Mesozoic to...
