Abstract - Summary 
(short description):
Unique isotopic and geochemical heterogeneity of kimberlites of the different emplacement phases is revealed within the Udachnaya pipe. Mantle source of the first phase of the mica kimberlite corresponds to the enriched mantle of the EM11-type (εNd = -4.8, 87Sr/86Sr(t) = 0.7078). For veined carbonatizated kimberlites as well as for other later kimberlitic phases the mantle source falls within the moderately depleted mantle (εNd = 4.2, 87Sr/86Sr(t) = 0.7050).
Key words: Udachnaya pipe, kimberlites, mantle source.
