| Abstract: | This paper describes the use of pyroxene compounds of clinopiroxene in mafic and ultramafic rocks (inclusions and layered outcrops) in the Canary Islands as geobarometric indicators of the depth of formation of different rock types. The upper mantle origin of peridotite and gabbro inclusions was confirmed, while a crustal character is proposed for the layered complexes. Finally, a scheme of Canary substrate is outlined. |
