    1. New aero-gravity results from the Arctic: Linking the latest Cretaceous-early Cenozoic plate kinematics of the North Atlantic and Arctic Ocean (pages 4044–4065)

      A. Døssing, J. R. Hopper, A. V. Olesen, T. M. Rasmussen and J. Halpenny

      Article first published online: 2 OCT 2013 | DOI: 10.1002/ggge.20253

      Key Points

      • Presentation of the largest aero-gravity survey acquired over the Arctic Ocean
      • Plate tectonic link between Atlantic and Arctic spreading west of Greenland
      • New plate reconstruction models are presented for the area north of Greenland
    2. Can a sheet-like low-velocity region form an elongated Large Igneous Province? (pages 3053–3066)

      Atsuko Namiki, Kenta Sueyoshi and Nozomu Takeuchi

      Article first published online: 28 AUG 2013 | DOI: 10.1002/ggge.20182

      Key Points

      • There exists a low-velocity region with sheet-like shape in the lower mantle
      • We performed experiments to investigate the stability of sheet-like upwellings
      • Less buoyant upwellings can ascend maintaining their sheet-like shapes

      Convergence of the Indian and Eurasian plates under eastern Tibet revealed by seismic tomography

      Heng Zhang, Dapeng Zhao, Junmeng Zhao and Qiang Xu

      Article first published online: 8 JUN 2012 | DOI: 10.1029/2012GC004031

      Key Points

      • The Indian and Asian lithospheric mantle is clearly imaged
      • A mantle diapir is detected between the Indian and Asian lithospheric mantle
      • The pattern of crustal flow is complex and may be induced by the mantle diapir

      Constraining the Jurassic extent of Greater India: Tectonic evolution of the West Australian margin

      Ana D. Gibbons, Udo Barckhausen, Paul van den Bogaard, Kaj Hoernle, Reinhard Werner, Joanne M. Whittaker and R. Dietmar Müller

      Article first published online: 25 MAY 2012 | DOI: 10.1029/2011GC003919

      Key Points

      • To constrain the extent of Greater India using evidence offshore West Australia
      • To develop a model that incorporates the new Jurassic data off NW Australia
      • To link the Jurassic and Cretaceous spreading corridors of NW Australia

      Insights on the kinematics of the India-Eurasia collision from global geodynamic models

      Sabin Zahirovic, R. Dietmar Müller, Maria Seton, Nicolas Flament, Michael Gurnis and Joanne Whittaker

      Article first published online: 4 APR 2012 | DOI: 10.1029/2011GC003883

      Key Points

      • Testing India-Eurasia collision kinematics using geodynamic models
      • Results indicate Greater India collided first with NeoTethyan back-arc basin
      • Long-lived Andean style subduction does not explain present-day mantle structure

      On recent seismic tomography for the western United States

      T. W. Becker

      Article first published online: 7 MAR 2012 | DOI: 10.1029/2011GC003977

      Key Points

      • All new western U.S. tomography models show the same patterns
      • Shear and compressional wave anomaly amplitudes are hugely different
      • Small-scale structure is mapped robustly, but interpretation for density unclear

      A geodynamic model of plumes from the margins of Large Low Shear Velocity Provinces

      Bernhard Steinberger and Trond H. Torsvik

      Article first published online: 18 JAN 2012 | DOI: 10.1029/2011GC003808

      Key Points

      • Sinking subducted slabs form a heavy chemical layer to dome-shaped structures
      • Slabs also push the thermal boundary layer toward the chemical domes
      • The TBL begins to rise at the steep edges of domes and forms mantle plumes
