Spreading continents kick-started plate tectonics by Rey, Patrice F., Coltice, Nicolas, Flament, Nicolas

“…The slow gravitational collapse of early continents could have kick-started transient episodes of plate tectonics until, as the Earth’s interior cooled and…”

What drives tectonic plates? by Coltice, Nicolas, Husson, Laurent, Faccenna, Claudio, Arnould, Maëlis

“…Does Earth's mantle drive plates, or do plates drive mantle flow? This long-standing question may be ill posed, however, as both the lithosphere and mantle…”

Spreading ridge migration enabled by plume-ridge de-anchoring by Mather, Ben, Seton, Maria, Williams, Simon, Whittaker, Joanne, Carey, Rebecca, Arnould, Maëlis, Coltice, Nicolas, Duncan, Robert

“…It has long been recognised that spreading ridges are kept in place by competing subduction forces that drive plate motions. Asymmetric strain rates pull…”
