P. Semenenko Institute of geochemistry, mineralogy and ore formation popup.description1 Study of genetically important structural components in meteorites, mainly in chondrites, which are or may be indicators of the key processes of origin and evolution of a mineral material in a pre-terrestrial period of the Solar System development popup.description2 The results of structure-mineralogical, chemical and spectroscopic studies of carbon-containing matter in a new primitive xenolith K4 and in a unique fine-grained rim of a high-temperature chondrule, bitumen-graphite inclusions in macrochondrule and in PC xenolith from the Krymka meteorite, features of a surface sculpture and structure of rare macrochondrules within 5 chondrites, metamorphic inclusions in a Fe,Ni-metal of ordinary chondrites and iron meteorites, and weathering products in meteorites are given. According to the study, a new type of carbonaceous material was discovered, a conclusion about the active exchange of minerals between different in PT conditions zones of agglomeration of the parent bodies of meteorites was made, direct evidence of the transformation of bitumen into polycrystalline graphite according to its purification from trace elements and their crystallization in the form of solid inclusions along the phase boundaries of graphite monocrystals was obtained, a conclusion about macrochondrules as the main source of the coarse-grained component of a matrix of unequilibrated chondrites was inferred.
