Fluid-assisted strain localization in the mantle


In collaboration with

Carlos J. GARRIDO

Why to study mantle shear zones?

Sampling

Fig. 1 - Outcrop of a ca. 2 km long peridotite shear zone, that progressively narrows from dozens of meters to less than a meter in the Ronda massif, southern Spain.
Fig. 2 - Photomicrograph of a shear zone thin section under cross polarized light.

Results

Fig. 3 - EBSD phase map of a thin section showing the redistribution of mineral phases inside the shear zone. Color coding indicates olivine (red), orthopyroxene (blue), clinopyroxene (green), spinel (gray) and amphibole (light blue).
