Olivine is the dominant component in kimberlites (~ 40–60 vol%), where it occurs as
individual grains of variable size (> 1 cm to< 100 μm) of xenocrystic and magmatic origin …

Kimberlite magmas are of economic and scientific importance because they represent the
major host to diamonds and are probably the deepest magmas from continental regions. In …

We present petrography and mineral chemistry for both phlogopite, from mantle-derived
xenoliths (garnet peridotite, eclogite and clinopyroxene–phlogopite rocks) and for …

We studied olivines from the Devonian pre-trap (the Ilbokich occurrence) and the Triassic
post-trap (the Chadobets occurrence) carbonate-rich ultramafic lamprophyres (UMLs) in the …

Olivine in kimberlites can provide unique insights into magma petrogenesis, because it is
the most abundant xenocrystic phase and a stable magmatic product over most of the liquid …

Olivine is the most abundant phase in kimberlites and is stable throughout most of the
crystallization sequence, thus providing an extensive record of kimberlite petrogenesis. To …

Complex core-rim zoning of Mg-Fe-Ni-Ca-Cr-Al-P in high-Mg olivine crystals from a tuff ring
of Shiveluch volcano, Kamchatka, enables reconstruction of the entire olivine crystallization …

Here we present major and trace element data for garnet and clinopyroxene from mantle-
derived peridotite xenoliths of the Grib kimberlite, the Arkhangelsk diamond province …

The petrography and mineral composition of a mantle-derived garnet peridotite xenolith from
the V. Grib kimberlite pipe (Arkhangelsk Diamond Province, Russia) was studied. Based on …

To provide new insights into the origin of megacrysts and metasomatism of the
subcontinental lithospheric mantle (SCLM), we present a detailed petrographic and …
