Average temperatures from the different thermometers are similar and higher in harzburgites (1106- 1036º C) than in lherzolites (1043- 867º C), and one pyroxenite shows similar T to harzburgites (1078º C). Low standard deviation for the T estimates reflects equilibrium in most samples for the thermometric reactions. Pressure estimates show high uncertainty, except for few samples, the pyroxenite included, which give consistent values (15.0- 9.6 kbar) within the spinel lherzolite field}, title = {Condiciones P-T en xenolitos mantélicos de los volcanes la Banya del Boc y el Puig d’Adri (Girona)}, title = {P-T conditions of mantle xenoliths from La Banya del Boc and Puig d’Adri volcanoes (Girona)}, author = {Oliveras, V. and Galán, Gumer}, }
