On The initiation of subduction
Journal of Geophysical Research: Solid Earth, 1991Estimates of shear resistance associated with lithospheric thrusting and convergence represent lower bounds on the force necessary to promote trench formation. Three environments proposed as preferential sites of incipient subduction are investigated: passive continental margins, transform faults/fracture zones, and extinct ridges.

Sediment subduction and frictional sliding in a subduction zone
Geology, 1980New experimental data for the mechanical and thermodynamic properties of clays at high pressure and high temperature are applied to model the frictional sliding in a subduction zone. The model is believed applicable because of the large volume of pelagic sediments that appear to have been subducted with the oceanic plate along active Pacific margins ...

Is there subduction on Venus? [PDF]
Physics World, 1992 How like the Earth is Venus? In particular, does Venus's surface exhibit the circulation of crustal material out of, and back into, its interior, as is seen in the plate tectonics that occurs on the Earth? Past space explorations have suggested not, but David Sandwell and Gerald Schubert of the University of California have now used recent data from ...

Plate tectonics is well established as an empirical description for modification of the Earth's outermost solid layer, although the dynamics of the plates are poorly understood. One view is that the plates are surface manifestations of the deep mantle convection which must inevitably occur if there are deepseated energy sources.

Conventional structure data from orogenic belts can be related to events of lithospheric plate subduction regardless of the great difference in depth range of the compared sets. Thrust fabrics and rotation zone fabrics are diagnostic of the two possible orientations of vergenz with respect to subduction and of events of flip, i.e., reversal in dip of ...

Stress orientations in subduction zones and the strength of subduction megathrust faults [PDF]
Science, 2015 Faults well oriented for failure A deck of cards will remain motionless while pressed on from above, but easily separates when sheared. Similarly, the ease by which geological faults rupture depends on the geometry of the fault relative to the size and direction of stress.

On the role of subducting oceanic plateaus in the development of shallow flat subduction
Tectonophysics, 2002Abstract Oceanic plateaus, aseismic ridges or seamount chains all have a thickened crust and their subduction has been proposed as a possible mechanism to explain the occurrence of flat subduction and related absence of arc magmatism below Peru, Central Chile and at the Nankai Trough (Japan). Their extra compositional buoyancy could prohibit the slab

Morphologically, mid-ocean ridges are the most complex and geologically active terrains on the seabed. They are now recognized as the places where the Earth’s oceanic crust is constructed (starting with the seminal paper of Vine and Matthews, 1963). Characterized by high topographic relief, the mid-ocean ridges are dominated by volcanic and tectonic ...

Rocks are subjected to increased pressure as they are buried during subduction. Contrary to general belief, a study suggests that peak pressures recorded in subducted rocks might not reflect their maximum burial depths.
