Paleogeographic reconstructions of the mid-Cretaceous, created on GPlates using time dependent raster files72. a Mollweide Projection. Pink shaded areas with a white outline represent modelled extent of active Large Igneous Provinces (LIPs)73. HALIP = High Arctic Large Igneous Province; OJP = Ontong Java Plateau; KP = Kerguelen Plateau; CLIP = Caribbean Large Igneous Province; MB = Mentelle Basin; WIS = Western Interior Seaway; EES = Eurasian Epicontinental Sea; GZ = Gongzha Section, Tibet6; 1138 = Ocean Drilling Program Site 113842; MBT = Maverick Basin, Texas22; VB = Vocontian Basin, France5; EB = Eastbourne, UK23; YG =Yezo Group, Hokkaido, Japan5; 1260 = Site 1260 B, Demerara Rise, Atlantic Ocean74; TB = Tarfaya Basin, Morocco23. b The proto-Indian Ocean region focused on the Kerguelen Plateau and the Mentelle Basin. Dashed purple arrow = mean direction of intermediate water mass (500–1500 m) flow during the Cenomanian75. Absolute ages of volcanic activity on the Kerguelen Plateau and named sub-sections of the LIP13. NKP = North Kerguelen Plateau, BR = Broken Ridge; SKP = South Kerguelen Plateau; CKP/EB = Central Kerguelen Plateau/Elan Bank.
