Fig. 5: Plan views of P-wave velocity anomalies of model VoiLA-P19 with reconstructed slab positions.
From: Subduction history of the Caribbean from upper-mantle seismic imaging and plate reconstruction
a Slice at 40–100 km depth, with the position of the slab subducted at 10 Ma along the current Lesser Antilles Arc (LAA), b Slice at 160–240 km with slab subducted along the Outer Lesser Antilles Arc (OAA) at 30 Ma. c Slice at 320–410 km with the position of slab subducted along the GAC/OAA at 50 Ma. d Slice at 410–530 km with positions of slab subducted along the GAC 50 and 60 Ma. e Slice at 530–660 km with positions of slab subducted 60 and 70 Ma. In yellow: Cuban part of the GAC. In green: Aves/Leeward Antilles part of the GAC. Slab positions are dashed to indicate possible deformation post subduction. The black diamond shows the location of the extinct spreading centre which is a likely location of a tear between the two slabs, black star indicates where the spreading centre subducted while still active, forming a slab window. Red labels mark our interpretation of the high-velocity anomalies as derived from subduction along the LAA, OAA or northern (nG) and southern (sG1 and sG2) part of the GAC.
