Garnet-driven mineral transitions explain the topography of Earth's 660-km seismic discontinuity (IMAGE)
Caption
Schematic illustration of the 660-km seismic discontinuity showing how coupled post-spinel and post-garnet transitions shape the boundary in the average mantle, cold subducting slabs, and hot mantle plumes, explaining its complex seismic structure.
