Kimberlites, megacrysts and related xenocrysts from southern and Central Africa: geochemistry and petrology
Kimberlites, megacrysts and related xenocrysts from twelve localities in central and southern Africa have been investigated with particular emphasis on megacryst petrogenesis, the evolution of the subcontinental lithospheric mantle (SCLM) beneath the northeastern Kasai Craton and the petrogenesis …
