Postspreading rifting in the Adare Basin, Antarctica: Regional tectonic consequences
[1] Extension during the middle Cenozoic (43–26 Ma) in the north end of the West Antarctic rift system (WARS) is well constrained by seafloor magnetic anomalies formed at the extinct Adare spreading axis. Kinematic solutions for this time interval suggest a southward decrease in relative motion between East and West Antarctica. Here we present multichannel seismic reflection and seafloor mappin...
متن کاملThe Consequences of Separation
When a child is removed from his parents three separate and distinct problems are created. A new home has to be found for him; his recovery from the shock of separation must be facilitated; thirdly, there is the difficult task of repairing the breach which has been made in the continuity of his experiences and memories. The energetic discussions which followed the publication of the Bowlby mono...
متن کاملControl of rheological stratification on rifting geometry: a symmetric model resolving the upper plate paradox
Numerical experiments reproduce the fundamental architecture of magma-poor rifted margins such as the Iberian or Alpine margins if the lithosphere has a weak mid-crustal channel on top of strong lower crust and a horizontal thermal weakness in the rift center. During model extension, the upper crust undergoes distributed collapse into the rift center where the thermally weakened portion of the ...
متن کاملMechanisms and Consequences of Macromolecular Phase Separation
Over a century ago, colloidal phase separation of matter into non-membranous bodies was recognized as a fundamental organizing principal of cell "protoplasm." Recent insights into the molecular properties of such phase-separated bodies present challenges to our understanding of cellular protein interaction networks, as well as opportunities for interpreting and understanding of native and patho...
متن کاملPlate bending at subduction zones: Consequences for the direction of plate motions
Bending of lithospheric plates at subduction zones is thought to be an important source of dissipation for convection in the Earth's mantle. However, the influence of bending on plate motion is uncertain. Here we use a variational description of mantle convection to show that bending strongly affects the direction of plate motion. Subduction of slabs and subsidence of oceanic lithosphere with a...
