Abstract

The mineralogical analysis is a highly effective method of prospecting diamond-hosting rocks. The main goal of investigating kimberlites rocks, the primary source of diamonds, is to examine the mineral composition of kimberlites. The microprobe analysis is currently the principal method to define the compositions of megacryst minerals from kimberlite rocks. In addition, determination of the groundmass mineral composition is important for evaluating the diamond potential of kimberlites. This paper presents results of studying groundmass of kimberlite from the pipes of the Alakit-Markhinsky field of Yakutian province. The distribution of minerals through rocks, their ratios and chemical composition of minerals depending on the texture-andstructural features were examination by microprobe JXA-8200.
