A study of the diamonds, diamond inclusion minerals and other mantle minerals from the Swartruggens Kimberlite, South Africa

While a clear and unequivocal model for the formation of diamonds is still lacking, the past few decades have seen a 'revolution' in the scientist's perception of mantle processes, particularly that regarding diamond formation. Kramers (1977) fIrst clearly recognised the ancient origin of diamonds from his studies of composited sulphide inclusions. However, it was not until mid-Archean ages were obtained from syngenetic garnet inclusions in diamond by Richardson et al. (1984), that it became generally accepted that most diamonds were in fact very much older than their kimberlitic hosts, and could therefore not have been precipitated from the kimberlite magma.
