Abstract

Fresh spinel-Lherzolite xenoliths occur within the pyroclastic components of the Aritain volcano, NE-Jordan. The average modal composition of the xenoliths is 67 vol.% olivine, 23 vol. % orthopyroxene, 9 vol. % clinopyroxene and 1.6 vol. % spinel. All xenoliths exhibit a protogranular texture. Selected electron probe analyses of enstatite, diopside, olivine, and spinel are given. Temperatures of their last equilibration range from 925° to 1,025°C. Pressure estimates based on the spinel-Lherzolite stability field restrict the xenolith source to a depth of 37 to 60 km. Up to 18 % XCr in spinel indicates an origin from a maximum depth of 60 km.
