The structure-mineralogical and chemical data of the most informative textural units of primitive meteorites - chondrules, fine-grained matrix and lithic fragments of preaccretion rocks - are given. A new kind of cosmic matter like carbonaceous chondrites, which compose graphite-containing xenolits in the Krymka chondrite, are found and investigated in details. It is established, the xenolits were formed in result of metamorphism and shock fragmentation of primary carbon-bearing rocks. The existence in space a highly-porous silicate matter, which composes primary bodies and partially regolite, is supposed on the basis of complex research of chondrules and matrix of the Saratov meteorite. These important results in the field of cosmic mineralogy can be used for decision of some essential problems of geology also. Product Description popup.authors popup.nrat_date 2020-04-03 Close
