The paper touches upon the relationships between kimberlite and basalt magmatism in the Nakyn field of the Yakutian kimberlite province. It was established, that the source for melts of pre-kimberlite basite was the ancient enriched lithosphere mantle ...

Comparative characteristics of diamonds from areas with a high density of kimberlite bodies
Background. This paper presents a comparative study into diamonds from kimberlite bodies of the Verkhnemunsky field (Zapolyarnaya, Novinka, Komsomolskaya-Magnitnaya and Poiskovaya), the results of which allow these minerals to be distinguished from those

On the presence of the postmagmatic stage of diamond formation in kimberlites
On nowadays multiphase and the facies heterogeneity of the formations are distinguished at the study of kimberlite pipes. Most researchers associate the formation of diamonds only with the mantle source.

Geotechnical Modelling for Kimberlite Pipes [PDF]
EKATI Diamond Mine is located some 200 km south of the Arctic Circle and 300 km northeast of Yellowknife in the Northwest Territories of Canada. It is a remote fly-in-fly-out site with road access limited to the winter ice road season. The operation currently consists of two active open pits and two underground operations.

A mantle origin for sulfates in the unusual “salty” Udachnaya-East kimberlite from sulfur abundances, speciation and their relationship with groundmass carbonates [PDF]
The Udachnaya-East pipe in Yakutia in Siberia hosts a unique dry (serpentine-free) body of hypabyssal kimberlite (

Petrogenetic processes in the ultramafic, alkaline and carbonatitic magmatism in the Kola Alkaline Province: a review [PDF]
Igneous rocks of the Devonian Kola Alkaline Carbonatite Province (KACP) in NW Russia and eastern Finland can be classified into four groups: (a) primitive mantle-derived silica-undersaturated silicate magmas; (b) evolved alkaline and nepheline syenites; (
