| Popis: | In the first part of the paper there is a description about genesis of meteorites, in particularly about stony meteorites– chondrites, since meteorite Jesenice is an ordinary L chondrite. Chondrules represent main part of the mass ofchondritic meteorites. For this reason the second part of the paper talks about morphology, texture, mineralogy andchemical properties of chondrules. Main theories about chondrule formation and other distinctive textures found inchondrites are also presented. The paper also presents a review across different meteorite classifications. Meteoriteclassifications differ depending on the geochemical and mineralogical properties of meteorites. In this paper are alsoused some new Slovenian terms correlated with the science of meteorites and mineral materials. Classification ofmeteorite Jesenice is based on its macroscopic and microscopic characteristics. We classified meteorite Jesenice onthe basis of shock metamorphosis, grade of weathering, petrological properties and chemical composition of olivine.We found out that meteorite Jesenice is weakly shocked weakly weathered undifferentiated low total iron ordinarychondrite. Our results are in agreement with findings of Bischoff and his colleagues. |
