Essay

A systematic search for foreign clasts in the Krymka and Saratov chondrites, their mineralogical, chemical and isotopic study with the aim to understend the origin of the foreign materials in the early Solar System was the main aim of the thesis. Graphit-containing material has been first found in meteorites. It composes fragments of preagglomeration rock in the Krymka chondrite and belongs to a new kind of cosmic material like carbonaceous chondrites.Fine-grained fragments in the Krymka chondrite are fragments of primary rocks, which were formed in result of accretion of unequilibrated mineral dust. Two kinds of highly-porous silicate material was determined and studed in the Saratov chondrite. They have a different origin.
