Mineralogical characterization of peridotite xenoliths from the Los Tormos volcano (Calatrava volcanic field)

Peridotite xenoliths from the Los Tormos volcano (Calatrava volcanic field)provide significant information about the lithospheric mantle of Central Iberia.Studied samples are classified as spinel-bearing lherzolite, harzburgite andwehrlite. Chemical composition of olivine and two pyroxenes shows sim...
