Chemical heterogeneity in the diamondiferous eclogite xenolith from the Udachnaya Kimberlite Pipe
journal contribution
posted on 2023-05-18, 04:19 authored by Stepanov, AS, Shatsky, VS, Zedgenizov, DA, Ragozin, ALThe 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].
