Influence of trench width on subduction hinge retreat rates in 3‐D models of slab rollback
David Robert Stegman,Justin Freeman,Wouter P. Schellart,Louis-Noel Moresi,David Alexander May +4 more
TL;DR: In this article, the authors investigate the time evolution of a progressive rollback subduction, measure the accompanying return flow in the upper mantle, and quantify the plate kinematics, showing that most of the negative buoyancy of the subducting slab is converted into a toroidal flow, and the remaining amount goes into driving flow parallel to displacement of the slab.

Rheological structure and deformation of subducted slabs in the mantle transition zone: implications for mantle circulation and deep earthquakes
TL;DR: In this paper, the authors investigated the rheological structure of subducted slabs of oceanic lithosphere in the mantle transition zone based on mineral physics observations incorporating grain-size, stress, temperature and pressure dependence of rheology.
Journal ArticleDOI
On the role of subducting oceanic plateaus in the development of shallow flat subduction.
TL;DR: In this paper, a numerical thermochemical convection model was used to simulate the subduction of an oceanic lithosphere that contains an 18 km-thick oceanic crustal plateau of 18-km thickness.
Journal ArticleDOI
Grain-size evolution in subducted oceanic lithosphere associated with the olivine-spinel transformation and its effects on rheology
TL;DR: In this paper, the role of grain-size reduction during the olivine-spinel transformation on rheological properties of subducting slabs on the basis of a scaling model for microstructural development during nucleation and growth was investigated.
Journal ArticleDOI
Experimental constraints on the depth of olivine metastability in subducting lithosphere
TL;DR: In this article, the authors derived new thermo-kinetic subduction zone models to predict the extent of olivine metastability within the stability fields of its high-pressure polymorphs, wadsleyite and ringwoodite.

Kinetics of Phase Change. I General Theory
TL;DR: In this paper, the theory of phase change is developed with the experimentally supported assumptions that the new phase is nucleated by germ nuclei which already exist in the old phase, and whose number can be altered by previous treatment.
Journal ArticleDOI
Kinetics of Phase Change. II Transformation‐Time Relations for Random Distribution of Nuclei
TL;DR: In this article, a relation between the actual transformed volume V and a related extended volume V1 ex is derived upon statistical considerations, and a rough approximation to this relation is shown to lead, under the proper conditions, to the empirical formula of Austin and Rickett.
Journal ArticleDOI
Granulation, Phase Change, and Microstructure Kinetics of Phase Change. III
TL;DR: In this paper, a comprehensive description of the phenomena of phase change may be summarized in Phase Change, Grain Number and Microstructure Formulas or Diagrams, giving, respectively, the transformed volume, grain, and microstructure densities as a function of time, temperature, and other variables.
