Microstructural evolution in deforming olivine-serpentine aggregates at subduction zones conditions using in-situ X-ray tomography
Abstract
Rheology and deformation of serpentinized peridotite play and important role in the flow and dynamicsof thesubducting slab. Antigorite, the high-temperature variety mineral of serpentinegroup, coexists with olivine in serpentinized peridotite at conditions of subduction zones.It is generally accepted that antigorite mechanical strength is lower than olivine at geological strain rates. Therefore,in abimineralicrock comprisingolivineandantigorite, deformation localization is expected to occur in the weaker antigoriterather than in olivine. Based on polymineralic rocks mechanical and microstructural behaviours (e.g., Handy, 1990), two mainend-memberconfigurations arepossible:thestrongolivine crystals formaloadbearing framework(LBF) that contains spaces filled with antigorite; or the antigorite governsthe bulk rheology of the aggregate by forming an interconnected weak layer(IWL), while the olivine crystals behave as clasts.The aim of this study is to observe at which conditions an IWL stage may be achieved under simple shear deformation in serpentinized peridotite at subduction zones conditions.Wecarried out torsion experiments at high pressures (HP, > 2 GPa) and high temperatures (HT, 400-600°C) on antigorite + olivine aggregates asaproxy for partially serpentinized peridotite. The experiments are coupled with in-situX-ray tomography on the PSICHE beamline at SOLEIL synchrotron. Weretrieve andquantify 2-Dand3-Dinformationon fabricsand/or microstructureevolutionsunder HP-HT, extent of interconnection(or connectivity), preferred microstructural directions and morphologyof the weak antigorite phase. We also perform post-mortemelectronmicroscopyanalysis onrecoveredsamplesofinteresttolinkour X-ray tomography observations to the plastic propertiesand/or deformation mechanism of the phases.Our results suggest that the total connectivity of the weak antigorite increases with thestrain extenttransferredtothesamples, withantigoritemineralsforming,insomecases,clear interconnected weak layers in agreement with IWL behaviour.The stronger olivinethen shows localizedlattice bending/rotationin clastsindicatinglocaldeformationaccommodatedby intracrystalline low-temperature plasticity.
