dc.description.abstractCoronitic gabbros of tholeiitic affinity croping out in the Segovia region in relation to ductile shear zones are studied in the present work. Mineral equilibria and thermobarometric calculation indicate that maximum P-T was close to 830°C and 7 kbar. Retrograde conditions of 525-650°C and 2-3.8 kbar are estimated. Maximum calculated PT conditions agree with the general clockwise metamorphic path established for this intracontinental collisional belt, which evolves from eclogitic conditions of around 775° C and 14 kb towards granulite facies conditions like the ones estimated for this metagabbrosen_US
