Full textDeformation in a shallow partially molten mantle: constraints from natural systemsWe analysed the interactions between melts and deformation in the upper mantle through detailed microstructural studies in two settings: a 100m section in the Moho Transition Zone (MTZ) of the Oman Ophiolite and plagioclase-rich lherzolites from the Lanzo massif (Alps). The MTZ section is characterized by a cm to m-scale layering; compositions range from dunites to gabbros à olivine. Parallelism between the layering and the foliation, diffuse layers limits, and alignment of mm-scale plagioclase-rich lenses in intermediate composition layers imply shear-controlled layering. All phases have crystal-preferred orientations (CPO), but olivine CPO varies depending on the layer composition. Layers with <70% olivine show strong [100] maxima parallel to the lineation (axial-[100] pattern). Layers with <50% olivine have [100] dispersed in the foliation and concentration of [010] normal to it (axial-[010] pattern). These changes occur repeatedly on the mm-scale, at the layers limits, providing strong evidence for deformation in presence of variable melt fractions. CPO in olivine-rich layers is consistent with high-temperature dislocation creep. Axial-[010] olivine CPO patterns imply transpression or sliding along preferentially-wetted (010) grain boundaries in melt-rich layers; they are accompanied by increased activity of [001] glide. Since the change in CPO symmetry is not associated with dispersion, instantaneous melt fractions must have remained <30-40%. The continuous variation in olivine CPO symmetry with decreasing olivine content implies therefore that the CPO depends on the strain cumulated in presence of melt rather than on the instantaneous melt fraction.Plagioclase-rich lherzolites in Lanzo are characterized by an anastomozed network of plagioclase-rich layers, which locally grades into a diffuse cm-scale planar compositional layering. Olivine and orthopyroxene show evidence for deformation by dislocation creep under high temperature conditions: undulose extinction, subgrains or kinks, sutured grain boundaries, but plagioclase forms elongated aggregates of crystals with interstitial shapes. All major phases (except clinopyroxene) show clear CPO, independent of the layer composition. The olivine CPO has an orthorhombic symmetry, with [100] parallel to the lineation and [010] normal to the foliation (and to the layering), but [010] maxima are stronger than [100] ones. These olivine CPO are intermediate between the two patterns observed in the Oman MTZ, consistently with the less developed segregation in Lanzo. Together these data imply that melts tend to concentrate in bands aligned in the shear plane, forming an anastomosed network that may grade with increasing shear into a planar layering. Instantaneous melt fractions remain below the solid matrix disruption threshold; the deformation is still essentially accommodated by dislocation creep in the solid matrix. Deformation in presence of melt results, however, in different olivine CPO with axial–[010] patterns and hence in a different seismic anisotropy. Shear-controlled compositional layering may also create a mechanical anisotropy, with a directional reduction of the shear viscosity parallel to the bands
