Ocean Basin Evolution and Global-Scale Plate Reorganization Events Since Pangea Breakup
R. Dietmar Müller,Maria Seton,Sabin Zahirovic,Simon Williams,Kara J. Matthews,Nicky M. Wright,Grace E. Shephard,Kayla T. Maloney,Nicholas Barnett-Moore,Maral Hosseinpour,Dan J. Bower,John Cannon +11 more
TL;DR: This paper presented 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.
Journal ArticleDOI
Global plate boundary evolution and kinematics since the late Paleozoic
Kara J. Matthews,Kayla T. Maloney,Sabin Zahirovic,Simon Williams,Maria Seton,R. Dietmar Müller +5 more
TL;DR: In this article, the authors 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 and Mesozoic-Cenozoic (230-0-Ma).

Atlas of the underworld : Slab remnants in the mantle, their sinking history, and a new outlook on lower mantle viscosity
Douwe G. van der Meer,Douwe G. van der Meer,Douwe J.J. van Hinsbergen,Wim Spakman,Wim Spakman +4 more
TL;DR: The Atlas of the Underworld as discussed by the authors is a compilation comprising subduction systems active in the past ~300Myr, assuming no relative horizontal motions between adjacent slabs following break-off, but without assuming a mantle reference frame.
Supporting Online Material for Major Australian-Antarctic Plate Reorganization at Hawaiian-Emperor Bend Time
Joanne M. Whittaker,R. D. Müller,G. Leitchenkov,H. Stagg,M. Sdrolias,C. Gaina,Alexey Goncharov +6 more
TL;DR: In this article, a marked bend in the Hawaiian-Emperor seamount chain supposedly resulted from a recent major reorganization of the plate-mantle system there 50 million years ago.
Journal ArticleDOI
Subduction-transition zone interaction: A review
TL;DR: A review of observational constraints and dynamic models highlights that neither the increase in viscosity between upper and lower mantle (likely by a factor 20-50) nor the coincident endothermic phase transition in the main mantle silicates (with a likely Clapeyron slope of -1 to -2 MPa/K) suffice to stagnate slabs as mentioned in this paper.

Constraints on seismic velocities in the Earth from traveltimes
TL;DR: In this article, a new empirical traveltime curves for the major seismic phases have been derived from the catalogues of the International Seismological Centre by relocating events by using P readings, depth phases and the iasp91 traveltimes, and then re-associating phase picks.
Journal ArticleDOI
Age, spreading rates, and spreading asymmetry of the world's ocean crust
TL;DR: In this article, the authors present a digital model of the age, spreading rate, and asymmetry at each grid node by linear interpolation between adjacent seafloor isochrons in the direction of spreading.

S40RTS: A degree-40 shear-velocity model for the mantle from new Rayleigh wave dispersion, teleseismic traveltime and normal-mode splitting function measurements
TL;DR: In this paper, a new collection of Rayleigh wave phase velocity, teleseismic body-wave traveltime and normal-mode splitting function measurements are used for modeling shear-velocity variation in Earth's mantle.
Journal ArticleDOI
When and where did India and Asia collide
TL;DR: In this article, the authors used field evidence from Tibet and a reassessment of published data to suggest that continent-continent collision began around the Eocene/Oligocene boundary (∼34 Ma) and propose an alternative explanation for events at 55 Ma.
Journal ArticleDOI
A new global model for P wave speed variations in Earth's mantle
TL;DR: In this paper, the authors present a tomographic model of 3D variations in mantle P wave velocity, parameterized by means of rectangular cells in latitude, longitude, and radius, the size of which adapts to sampling density by short-period (1 Hz) data.
