Fig. 6: Two dipping cross-sections along the upper-mantle slab anomalies.
From: Subduction history of the Caribbean from upper-mantle seismic imaging and plate reconstruction
Locations of the cross-sections are indicated on Fig. 3a. a Cross section M along the Lesser Antilles Arc. Gu—Guadeloupe, Ma—Martinique. b Cross section T along the slab from Hispaniola to St Kitts. DR—Dominican Republic (Hispaniola), PR—Puerto Rico. Proposed interpretations are marked with arrows: green arrows indicating hydrated mantle wedge, R1, R2 positions of the subducted Proto-Caribbean ridge and Fz—location of a potential tear along a fracture zone.
