چکیده
Within the areas of Ulakhan-Kurung-Yuryakh and Bestyakh Malo-Botuobinsky district, in Syuldyukar kimberlite field Ygyattinsky carbonate-terrigenous deposits Upper Cambrian period revealed signs ancient formation-oxidation gray-colored coal-bearing, terrigenous carbon-Permian deposits, fractured commonly found on rocks underlying carboniferous weather crust. The data distribution correlation U Th, Sc, V confirmed formation oxidation zone. ore-forming significance infiltration hypergenic processes was by X-ray fluorescence analysis Sc concen- tration Сarboniferous Triassic-Jurassic weathering crusts, Late Paleozoic sediments, Ulakhan-Kurung-Jurassic area, Nakyn diamond-bearing fields. In latter, we identified promising ore occurrences crusts developed kimberlites Middle basites. series are particular interest diamond mining area Nyurbinsky GOK AK ALROSA (PAO).
