TLDR
In this article, a hybrid plate motion reference frame that permits the calculation of longitude back to Pangean assembly at ~ 320-Myr ago was devised, where most reconstructed Large Igneous Provinces (LIPs) of the past 300 million years were placed radially above the edges of the Large Low Shear wave Velocity Province (LLSVPs) in Earth's lowermost mantle.About:

TL;DR: In this paper, a new type of global plate motion model consisting of a set of continuously-closing topological plate polygons with associated plate boundaries and plate velocities since the break-up of the supercontinent Pangea is presented.

TL;DR: A significant number of new palaeomagnetic poles have become available since the last time a compilation was made (assembled in 2005, published in 2008) to indicate to us that a new and significantly expanded set of tables with palaeOMagnetic results would be valuable, with results coming from the Gondwana cratonic elements, Laurentia, Baltica/Europe, and Siberia as mentioned in this paper.

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).
Journal ArticleDOI
Gondwana from top to base in space and time
TL;DR: Gondwana is reviewed from the unification of its several cratons in the Late Neoproterozoic, through its combination with Laurussia in the Carboniferous to form Pangea and up to its progressive fragmentation in the Mesozoic.

Plate tectonics in the late Paleozoic
Mathew Domeier,Trond H. Torsvik +1 more
TL;DR: In this article, a model for the late Paleozoic (410-250 million years ago) is presented, together with a review of the underlying data, which can be used for numerical mantle modeling, and serve as a general framework for understanding late paleozoic tectonics.

Free software helps map and display data
Paul Wessel,Walter H. F. Smith +1 more
TL;DR: The Generic Mapping Tools (GMT) is introduced, which is a free, public domain software package that can be used to manipulate columns of tabular data, time series, and gridded data sets and to display these data in a variety of forms ranging from simple x-y plots to maps and color, perspective, and shaded-relief illustrations.

Convection Plumes in the Lower Mantle
TL;DR: The concept of crustal plate motion over mantle hotspots has been advanced to explain the origin of the Hawaiian and other island chains and the origin the Walvis, Iceland-Farroe and other aseismic ridges as discussed by the authors.
Journal ArticleDOI
Finite-Frequency Tomography Reveals a Variety of Plumes in the Mantle
TL;DR: In this article, the authors present tomographic evidence for the existence of deep-mantle thermal convection plumes, including six well-resolved plumes that extend into the lowermost mantle: Ascension, Azores, Canary, Easter, Samoa and Tahiti.
Journal ArticleDOI
Three distinct types of hotspots in the Earth's mantle
TL;DR: The origin of mantle hotspots is a controversial topic as mentioned in this paper, and only seven (primary) out of 49 hotspots meet criteria aimed at detecting a very deep origin (three in the Pacific, four in the Indo-Atlantic hemisphere).
Journal ArticleDOI
Complex Shear Wave Velocity Structure Imaged Beneath Africa and Iceland.
TL;DR: A model of three-dimensional shear wave velocity variations in the mantle reveals a tilted low velocity anomaly extending from the core-mantle boundary region beneath the southeastern Atlantic Ocean into the upper mantle beneath eastern Africa, suggesting that Cenozoic flood basalt volcanism in the Afar region and active rifting beneath the East African Rift is linked to an extensive thermal anomaly at the CMB.
