About >50 zicons from the kimbelite and carbonatite small bodied were analyzed Nikolaev Institute of Inorganic Chemistry SB RAS, Novosibirsk, Russi by LAM ICP MS method They shoes variation of the TYRE and REE levels and altitude of the naximunu of Zr Hf and Ta NB / The similarity of the Lu/Hf isotopy sygggest that all kimberlites and carbonatite in general are coherent but derived from the different levals in mantle columns. The ages from zircons are varying from Upper triasssic to prevailing Late Jurassic Mostrly they are transparent and have now fractures beein edial for the geochemical studioes
