Abstract
[EN] The Herbeira ultramafic massif is located in the structural upper portions of the Cabo Ortegal Variscan Complex, NW Galicia, which form part of a thrust sheet that shows a complex deformational evolution. An important strike-slip fault, the Trans Herbeira Fault, divides the massif into two different zones. The eastern one is composed of amphibole bearing harzburgites, whilst the western one has a more complete lithological succession: basal harzburgite, lower dunite, medium pyroxenite and upper dunite. Equigranular and porphyroclastic microfabrics are observed in these rocks under optical microscope and SEM, providing evidence of a succession of several tec...
