Distribution of kimberlite and aillikite in the Diamond Province of southern West Greenland: A regional perspective based on groundmass mineral chemistry and bulk compositions

Lithos, 2009
A regional study of dike and sill occurrences of kimberlitic rocks in terms of xenolith and megacryst assemblages from the diamond province in southern West Greenland demonstrates very systematic variation in the composition of melts across the margin of the Archaean core of the North Atlantic craton.

OLIVINE FROM NAMUAIY PIPE AILLIKITE, KOLA ALKALINE PROVINCE: THE PRIMARY MELT EVOLUTION AND RELATION TO KIMBERLITE MAGMATISM

Доклады Российской академии наук. Науки о Земле / Doklady Earth Sciences
This study presents petrographic and mineral chemical data for olivine in aillikites from the Namuaiy pipe intruded into the Khibiny Massif, the Kola Alkaline Carbonatite Province. Two distinct olivine populations are identified: phenocrysts and xenocrysts. The phenocrysts crystallized from the aillikite melt, whereas the xenocrysts were entrained from
