From: Kimberlite eruptions driven by slab flux and subduction angle
Evolution of flat slab subduction along North America. (a) Flat slab subduction of the Farallon Plate is caused by the Shatsky Rise which enters the trench at 95 Ma. (b) Much of the Shatsky conjugate is consumed by 70 Ma by which time the Farallon underplates much of central USA, producing tectonic uplift associated with the Laramide Orogeny. (c) At 50 Ma the Farallon plate is removed from the base of overriding continental lithosphere resulting in widespread kimberlite eruptions. Black polygons indicate reconstructed large igneous provinces, grey polygons indicate inferred LIP conjugates, arrows indicate absolute plate velocity. Maps were generated using Cartopy21.
