Kinematics, topography, shortening, and extrusion in the India-Eurasia collision
We examine the problem of partitioning between shortening and extrusion in the India-Asia collision since 45 Ma. We compute the amount of shortening expected from the kinematics of India's motion with respect to Eurasia, using the reconstruction at collision time to put bounds on the possible amounts of surface loss within Greater India and within Eurasia. We then compute the amounts of surface...

متن کاملInsights 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 کاملInvestigation of the strength and trend of seismic anisotropy beneath the Zagros collision zone
The Zagros collision zone is known as an active tectonic zone that represents the tectonic boundary between the Eurasian and Arabian plates. A popular strategy for gaining insight into the upper mantle processes is to examine the splitting of seismic shear waves and interpret them in terms of upper mantle anisotropy and deformation. Core phases SK(K)S from over 278 earthquakes (MW ≥ ...
متن کاملDeep Structure of the Northeast Tibetan Collision Zone: INDEPTH IV The Himalaya-Tibet Collision Zone
The Himalayan Mountain Belt and adjacent Tibetan Plateau (Figure 1) remain the world’s foremost natural laboratory for investigation of continental collisional tectonics. The continuing debate over how the Asian continent has responded to the embedding of the Indian subcontinent has variously revolved around concepts such as distributed shortening (e.g. Dewey and Burke, 1973), wholesale contine...
