Slab Temperature Evolution Over the Lifetime of a Subduction Zone
Geochemistry, Geophysics, Geosystems, 2021 The thermal evolution of subducting slabs controls a range of subduction processes, yet we lack a robust understanding of how thermal structure develops over a subduction zone's lifetime. We investigate the time‐dependence of slab thermal structure using

Multi‐Hazard Shaking‐Tsunami Fatality Risk Estimation for Coastal Communities
Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT This study develops a multi‐hazard fatality risk model for a coastal community (Tofino) on Vancouver Island, Canada, subjected to earthquake‐tsunami threats from the Cascadia subduction megathrust events. The model incorporates variable population distributions and uncertain fatality rate models, in addition to other key model components, such

Mesozoic–Cenozoic Thermochronology of the Tarim–Southern Tianshan System, NW China
Geological Journal, EarlyView.Tectonothermal history of the Tarim–Southern Tianshan system compared with the major tectonic events at far‐field plate margins. ABSTRACT The Tarim Basin, an oil‐bearing basin in northwest China, is tectonically and sedimentologically linked to the Southern Tianshan Orogenic Belt.

Numerical analysis of deformation in the upper part of subduction zones [PDF]
, 1981 The stresses and deformation in an accretionary prism, and the crystalline basement behind and beneath it, have been modelled using finite element analysis, assuming a visco-elastic Maxwell rheology for the rocks involved.

Geological Journal, EarlyView.Coupled dissolution‐reprecipitation of early formed Cd‐, Fe‐, Ag‐ and Sb‐poor sphalerite through interaction with high‐temperature and high‐sulphur fugacity Cu‐rich fluids, responsible for the formation of the yellow ores, resulted in the formation of Cd‐, Fe‐, Ag‐ and Sb‐rich, heavily chalcopyrite‐diseased sphalerite and enrichment of critical metals ...

Contribution of ultramafic rocks in central Sanandaj-Sirjan zone to the characterizing of physio-chemical condition during initiation of subduction [PDF]
پترولوژی, 2018 In the central part of the Sanandaj-Sirjan zone, there is an ultramafic rock exposure (hornblendite and pyroxenite) adjacent to Molataleb felsic complex completely located between Azna and Aligoodarz towns.

Plate motion and plume-induced subduction initiation
, 2021 Impingement of a hot buoyant mantle plume head on the lithosphere is one of the few scenarios that can initiate a new subduction zone without requiring any pre-existing weak zones. This mechanism can start subduction and plate tectonics on a stagnant lid

Notable Impact of Paleotectonic Stress on Gold Mineralisation in the West Qinling Orogen
Geological Journal, EarlyView.By applying fuzzy clustering and multiple inverse methods, we systematically processed the data of vein and fault slip in this ore deposit to reveal the transition of orogenic geological environment and paleotectonic stress field. Our research results show two different stress states: the northwest–southeast extensional stress field and the northeast ...

A numerical study of the dynamics of subduction [PDF]
, 1988 The mechanics and dynamics of subduction have been studied using 2-D finite element analysis. Two finite element formulations have been employed; one formulation for Newtonian viscous flow and one formulation for linear elasticity and viscoelasticity ...

, 2021 We perform numerical modelling to simulate the shortening of an oceanic basin and the adjacent continental margins in order to discuss the relationship between compressional stresses acting on the lithosphere and the time dependent strength of the mid ...
