Semenenko Institute of Geochemistry, mineralogy and Ore Formation popup.description2 The data on studies of a chondrites fine-grained material as an important accretional product of protoplanetary nebula mineral dust, of nanograins, of new or rare minerals, and of minerals as indicators of evolution conditions of meteorites parent bodies in a space and meteorites on the Earth are given. Three genetic types of nanometer-sized mineral grains (primitive condensing, metamorphic and exogenous) and a native tungsten are for the first time identified in meteorites. The characteristic of a primitive material within the Krymka chondrule rims is presented: the conclusion on chemical inhomogeneity of a mineral dust of a protoplanetary nebula, which could have both spatial and chronological character, is made. Structural-mineralogical features of the iron nickel and iron sulfides within a primitive xenolith of the Allende carbonaceous chondrite and within the shocked ordinary chondrites are studied. Morphological features of the iron phosphides within pallasites are for the first time studied. Mixtures of iron oxides and oxyhydroxides as main products of a Fe,Ni-metal weathering are detected.
