We present a revised global plate motion model with continuously closing plate boundaries
ranging from the Triassic at 230 Ma to the present day, assess differences among alternative
absolute plate motion models, and review global tectonic events. Relatively high mean
absolute plate motion rates of approximately 9–10 cm yr− 1 between 140 and 120 Ma may
be related to transient plate motion accelerations driven by the successive emplacement of a
sequence of large igneous provinces during that time. An event at∼ 100 Ma is most clearly …
