Description
The Gibeon Kimberlite Province, southern Namibia, comprises numerous, 70-80 Ma old kimberlite pipes and dykes commonly containing abundant mantle and crustal xenoliths. We dated by SHRIMP II zircons from a garnet peridotite xenolith (Pipe Hanaus 1). The xenolith consists of garnet, orthopyroxene, clinopyroxene and, almost completely serpentinised, olivine. Crystallisation P-T conditions range between ca. 3.3 GPa, 910 °C (core composition of minerals) and ca. 3.5 GPa, 1000 °C (rim composition)....[Show more]
