Fellow ER1 Host Institution ETH Duration 24 months Start Date M6
Project title: Physics of multiscale fluid-melt migration across the deforming subduction interface-WP2

Supervisor name: May (ETH)dave.may@erdw.ethz.ch// Advisory Panel: Gerya ( taras.gerya@erdw.ethz.ch )/AF CONSULT/Garrido (carlos.garrido@csic.es)/Delescluse delescluse@geologie.ens.fr(ETH/ AF CONSULT/CSIC/CNRS)PhD enrolment: Y
Objectives: Testable numerical models for fluid/melt transport
Tasks and Methodology:

  • Study (in 2D and 3D) the percolation of reacting fluid and/or melt phases through the deforming subduction interface (ie, across a solid, multi-layered and mechanically mixed rock matrix).
  • Realistic visco-elasto-brittle/plastic rock rheologies, variable viscosities of fluid/melt phases and feedbacks between rock deformation, porosity and permeability will be systematically investigated. Links to projects of ESRs 2, 3 and 12.

Methods: numerical modelling, rheology, thermodynamics and kinetics of fluid/melt-rock interactions.
Results: Deliverable: Quantitative testable models of fluid/melt transport and chemical and rheological fluid/melt-rock interactions in subduction zones.
Dissemination: International conferences, Annual workshops, Outreach (see § 5.3)
Planned secondment: AF Consult, 3 months (10,17,18)Bring in the modelling expertise of coupled processes of multi-phase multi-component flows through deformable porous rocks.
Risk assessment: No risk

 

 

Fellow ER2 Host Institution UPMC Duration 24 months Start Date M6
Project title: Impact of composite rheologies for mixing processes at the plate interface

Supervisor name: Burov (UPMC)evgenii.burov@upmc.fr// Advisory Panel: Le Pourhiet (laetitia.le_pourhiet@upmc.fr )/Sallares  (vsallares@cmima.csic.es)/Karastathis (Karastathis@noa.gr )/Meier (meier@geophysik.uni-kiel.de) (UPMC/ CSIC/NOA/CAU)PhD

enrolment: Y
Objectives: Rheological/geodynamical/geochemical/seismological/2D-3D numerical thermomechanical
Tasks and Methodology:

  • model complex mixing processes at the plate interface at high spatial (from outcrop to regional scale) and temporal resolution by applying state-of-the art 2D numerical thermomechanical codes and developing upscaling law for mixing to be used in 3D codes.
  • Rheological, geodynamical, geochemical and seismological implications will be tested against constraints from structural,
  • petrological, geochemical and seismic data generated in other ESR/ER projects. Links with all WP3 projects.

Methods: modelling, mechanical mixing.
Results: Deliverable: impact of composite rheologies on and along the deforming plate interface.
Dissemination: International conferences, Annual workshops, Outreach (see § 5.3)
Planned secondment: CSIC, 6 months (12, 16, 17, 18, 19, 20)Link modelling of rock rheology with physical properties of the plate boundary zone from geophysical measurements
