Abstract

The first studies of diamond-hosted inclusions in xenoliths have demonstrated that the compositions of inclusions and minerals in xenoliths may differ substantially [1]. It was noted that a higher K content in clinopyroxene as compared with that in the matrix is among the most important differences [2]. The Mir Pipe yielded diamonds with numerous garnet and pyroxene inclusions with highly variable compositions [3, 4]. Some authors explain these compositional variations in inclusions by fractionation from the silicate melt [3].
