Abstract
The object of study is the products of the Zhamanshin crater: tektites – irgisites, subtektites, zhamanshinites. The features of morphology and the compositions of products were determined. In the distribution of rare earth elements of irgisites Eu and Ce anomalies appeared. The crystallized components of jamanshinite consist of phayalite, ferrosilite, magnetite. Large inclusions of zhamanshinite are represented by a solid solution of copper and boron, small ones by galenite with impurities of iron and tungsten. Among the accessor minerals of subtektites, xenotime, iocyte, coesite were found. The proximity of the mineral compositions of subtektites and a number of comets was confirmed.
