Extended Data Fig. 1: Modelled fracture zones.
From: Variable water input controls evolution of the Lesser Antilles volcanic arc
a, Modelled fracture zones in the central Atlantic overlaid on an oceanic crust age grid from ref. 13. Coloured stars denote conjugate points associated with opening of the equatorial Atlantic at either end of the Vema (green stars) and Doldrums (yellow stars) fracture zones, and between the Demerara Rise and African continental margin (red stars). b, Modelled fracture zones overlaid on satellite free-air gravity55. Red ellipse marks the location of the proto-Caribbean/Atlantic boundary.
