However, the nature of this correlation is not yet understood. In this study we examine assemblages of oxide minerals in different kimberlite facies aiming to constrain crystallisation conditions and ...

Among the more curious materials that occur naturally on the Earth are volcanic rocks called kimberlites. Unusually rich in magnesium, many of them also host notable quantities of elements as ...

THE origin of the volcanic pipes of South Africa and the genesis of the diamonds contained in their “blue-ground” filling are as productive of controversy as that other geological puzzle—the ...

and the subordinate phlogopite-rich coherent facies (HKP) in Snap Lake kimberlite, and among the four studied Ekati kimberlites. The differences in the emplacement of Snap Lake dyke and Ekati ...
