Fig. 7: Interpretation of tomotectonic analysis of three different pre-Cenozoic SLIPs.
From: Catastrophic slab loss in southwestern Pangea preserved in the mantle and igneous record
a Jurassic Chon Aike Magmatic Province104, b Upper Cretaceous Okhotsk-Chukotka volcanic belt102, and c Lower to Upper Cretaceous Whitsunday volcanic province100. The mantle structure in a and b support a context with active subduction during Chon Aike and Okhotsk-Chukotka SLIPs, whereas in c an arrested subduction setting is inferred for the Whitsunday SLIP. Mantle tomography slices are from the UU-P07 seismic tomography model45 and overlaid plate reconstructions are from Mathews et al.46. The original tomotectonic analysis is found in Supplementary Fig. S10.
