Extended Data Fig. 3: Full-waveform seismic tests.
From: Seismic imaging of a basaltic Lesser Antilles slab from ancient tectonics
Panels a–c illustrate the compositional fields of cases MM, LBA and LBR, respectively. Corresponding shear wave velocity gradient fields are shown in panels d–f, whereas the migrated synthetic receiver function results are presented in panels g–i. A superdeep 660 only appears in models with a large basalt accumulation in the slab.
