Constraints on shallow mantle viscosity from morphology and deformation of fast‐spreading ridges
[1] We show that the morphology and the deformation of a fast spreading ridge constrain shallow upper mantle viscosity. A fast spreading center is simulated in a numerical model that couples tectonic deformation due to plate spreading and periodic dike emplacements. The amount of magma intruded into dikes or extruded is enough to make a 7 km thick crust and the axial lithosphere is fixed at ∼2 ...
متن کاملGlobal slab deformation and centroid moment tensor constraints on viscosity
[1] We analyze moment tensor solutions from deep subduction zone earthquakes to determine global slab deformation patterns. Inferred strain rates are compared to predicted deformation patterns from fluid models to help constrain the first‐order radial and lateral viscosity structure of the Earth. While all slabs that reach the lower mantle are compressed at their tip, intermediate depth pattern...
متن کاملConstraints on lithosphere net rotation and asthenospheric viscosity from global mantle flow models and seismic anisotropy
[1] Although an average westward rotation of the Earth’s lithosphere is indicated by global analyses of surface features tied to the deep mantle (e.g., hot spot tracks), the rate of lithospheric drift is uncertain despite its importance to global geodynamics. We use a global viscous flow model to predict asthenospheric anisotropy computed from linear combinations of mantle flow fields driven by...
متن کاملAxial Structure of Fast Spreading Mid - Ocean Ridges : Implications for Overlapping Spreading Centers
Studies of the structure of mid-ocean ridges and the processes involved at these accreting plate boundaries have played an important role in the development of plate tectonics models over the last two decades. During this time our concept of the accretion/spreading process has evolved from a two-dimensional, steady-state picture to a three dimensional, time-dependent view of the volcanism and r...
متن کاملOn origin of near-axis volcanism and faulting at fast spreading mid-ocean ridges
At fast and superfast spreading mid-ocean ridges, such as the East Pacific Rise, a plate boundary is defined by a narrow (tens to hundreds of meters wide) neovolcanic zone within which the bulk of the upper oceanic crust is created. However, detailed near-bottom observations indicate that the volcanic construction may occasionally persist several kilometers off of the ridge axis. It has been pr...
