Complex of researches (chemical, mineralogical, X-ray phase, rare-earth, isotopic analyses) of volcanogenic-sedimentary rocks, composing basal horizon of the Osipayskaya formation of the Carnian stage in the middle course of Lena river ((Bulkur anticline) (Grakhanov, Smelov 2010, Proskurin et al, 2012), where diamonds of V and Vii variety according to L.Y. Orlov classification, was performed. Granite, ilmenite, spinellide, rutile are identified in rocks among minerals of heavy fraction. According to X-ray phase an...

Inclusions in diamond associated minerals are additional information about the formation of minerals in the depths of the mantle. Considerable attention is paid to the study of rutile inclusions in garnets in literature. Until now, there is no consensus on formation of oriented needle-like inclusions, some authors consider them to be epitaxial intergrowths, others ? exsolution. This article contains results of the study of eclogitic garnets from heavy fraction of diamondiferous volcanogenic sedimentary rocks of th...
