Abstract (in english)
   A large set of irghizites - impact glasses from the Zhamanshin crater in Kazakhstan - was analyzed by methods of activation analysis. Geochemical characterization of the glasses allowed to assign the impactor to ordinary chondrites and estimate its fraction in irghizites between 4 and 21 %. Possible source materials and impact processes leading to irghizite formation have been outlined.
