Semenenko Institute of geochemistry, mineralogy and ore formation popup.description2 The results of structural-mineralogical and chemical studies of a carbon-bearing material and rare shock-melted areas of chondrites, filiform mineral crystals, and terrestrial weathering products in different types of meteorites are given. For the first time, large bitumen inclusions in chondrites, as an important indicator of pre-accretional nature of organic material in the parent bodies, were revealed and studied by mean of electron microscope instead of chemical extraction. An important conclusion about the migration nature of the bitumen, probably due to impact processes during prolonged evolution of primary organic compounds in the parent bodies was inferred. A detailed study of structural and mineralogical characteristics and redistribution features of chemical elements between silicates, metal and troilite in chondrites in result of their complete shock-melting in situ allowed to clear up the PT-parameters of a shock metamorphism in a postaglomeration period and its effect on the primary mineral characteristics. It is shown that the filiform mineral crystals in chondrites, iron and iron-stone meteorites have different nature and are thin indicators of early physical-chemical processes in the Space.
