Abstract The Arbarastakh Neoproterozoic ultramafic carbonatite complex is located in the
southwestern part of the Siberian Craton (Aldan Shield) and contains ore-bearing Zr–Nb …

Abstract The Xiarihamu Ni deposit is located in the East Kunlun orogenic belt in the northern
part of the Qinghai-Tibet plateau. The regional tectonic setting, lithology, and mineralogy …

In this study, we discuss mineral chemistry data, melt inclusion study results, and report Ar–
Ar phlogopite age for the aillikite dikes of the Arbarastakh alkaline-carbonatite complex on …

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 …

Olivines are the dominant phase of kimberlites and the majority of grains display distinct
compositional zoning with xenocrystic cores surrounded by magmatic rims. Previous work …

Mesozoic diamondiferous lamproite pipes occur along the Kapamba River within the
Luangwa Valley of eastern Zambia, which is a ca. 300–200 Ma old Karoo-age precursor …

The petrogenesis of temporally and spatially associated carbonatitic and deeply derived
carbonated alkaline silicate magmas provides an opportunity to gain insights into the nature …

Kaapvaal lamproites, also known as orangeites, are H 2 O-rich, diamondiferous, highly
micaceous, ultrapotassic rocks. Olivines in kimberlites have been shown to be extremely …

The study reports major and trace element compositions of olivine in lamprophyre and
related nephelinite dykes with well documented petrography and geochemistry from two …

Aillikites are carbonate-rich ultramafic lamprophyres often associated with carbonatites.
Despite their common field relationships, the petrogenetic links, if any, between aillikites and …
