Insights on the kinematics of the India-Eurasia collision from global geodynamic models
[1] The Eocene India-Eurasia collision is a first order tectonic event whose nature and chronology remains controversial. We test two end-member collision scenarios using coupled global plate motion-subduction models. The first, conventional model, invokes a continental collision soon after 60 Ma between a maximum extent Greater India and an Andean-style Eurasian margin. The alternative scenari...
متن کاملRecent geodynamic regime of the Eurasia – North American interplate boundary: Evidences from seismology of Arctic
The paper considers seismological evidences on a geodynamic regime in the Arctic segment of the interplate boundary between Eurasian and North American lithosphere plates. A scope of earthquakes occurred in the Mon, Knipovich and Gakkel mid-ocean ridge belts (MORB) has been made, and distribution of doublecouple (DC) and non-double-couple (NDC) sources has been evaluated. As revealed, the DC ev...

متن کاملKinematic Model of Active Deformation in Central Asia
The velocity field of present-day deformation in Central Asia is modelled using a set of four rotating blocks (Siberia, Tarim, Tibet, India) on a spherical earth. A best-fit is inverted on the basis of estimated shorteningrates across the main thrust zones (Himalayas, Tien Shan) and measured slip-rates along the principal strike-slip faults (Altyn Tagh and Karakorum) separating those blocks. Th...
متن کاملA 3-D geodynamic model of lateral crustal flow
Although the Andes are believed to have resulted mainly from crustal shortening, the shortening history remains debated and appears to require lateral (along-strike) crustal flow. Three-dimensional viscous flow modeling shows that, within geological uncertainties, the Andes may have been produced by either Neogene shortening alone or with significant preNeogene shortening. These scenarios requi...
