Results of geochemical studies of suevites of the Kara astrobleme (Pay-Khoy) produced by a new approach based on square microprobe analysis of suevite matrix and consolidated impact melts with multivariate statistics have been described for the first time. At list three suevite varieties have been divided which are essentially differ by geomorphological, mineralogical, petrological and geochemical criteria. The protoliths of the initial rocks of the target for the suevite varieties have been supposed on the basis of a complex analysis.
