Abstract
Many aspects of deep-time Earth System models, including mantle convection, paleoclimatology, paleobiogeography and the deep Earth carbon cycle, require high-resolution plate models that include the evolution of the mosaic of plate boundaries through time. We present the first continuous late Paleozoic to present-day global plate model with evolving plate boundaries, building on and extending two previously published models for the late Paleozoic (410–250 Ma) and Mesozoic-Cenozoic (230–0 Ma). We ensure continuity during the 250–230 Ma transition period between the two models, update the absolute reference frame of the Mesozoic-Cenozoic model and add a new Paleozoic reconstruction for the Baltica-derived Alexander Terrane, now accreted to western North America. This 410–0 Ma open access model provides a framework for deep-time whole Earth modelling and acts as a base for future extensions and refinement.
This model is available with a default mantle reference frame, a hybrid reference frame using moving hotspots and a true polar wander corrected paleomagnetic reference frame (see paper for details) as well as with a paleomagnetic reference frame. For times before 83 Ma, the Pacific is shifted to maintain relative motions with the circum-Pangea continents – largely due to the fact that no paleomagnetic reference frames exist that extend to the birth age of the Pacific Plate. The paleomagnetic reference frame is based on data from Torsvik, T. H., Van der Voo, R., Preeden, U., Mac Niocaill, C., Steinberger, B., Doubrovine, P. V., van Hinsbergen, D.
