Abstract

A mineralogical and petrological study of some mantle xenoliths (harzburgites, Iherzolites, pyroxenites) from the Cat 115 pipe (Angola) has been carried out. Monomineral and two-mineral thermobarometers have been applied in order to define the geotherm beneath the Lunda kimberlitic province (Angola), which is close to the -38 mW/m(2) proposed by Pollack and Chapman (1977). The results of this study show that most of the analysed xenoliths equilibrated inside the diamond stabillty field. These results are consistent with the fertile character of the kimberlite, and can be useful for other kimberlites in the Lunda domain.
