For the purposes of this study, H3 type ordinary chondritic meteorite Abbott was selected. SEM/EDS allows identification and characterisation of mineral phases, whose size is below the resolution of an optical microscope. Mineral phases in chondrules and interstitial matrix were located in backscattered electron (BSE) mode and were assessed from atomic proportions of constituent elements, obtained by the EDS analysis. SEM/EDS analyses of mineral phases showed that Abbott meteorite is characterised by Fe-rich (Fe, Ni)-alloy kamacite, Fe-sulphide troilite or pyrrhotite, chromite, Mg-rich olivine, orthopyroxene bronzite or hypersthene, clinopyroxene Al-diopside, acid plagioclase oligoclase, accessory mineral chlorapatite and secondary minerals Fe-hydroxides (goethite or lepidocrocite). Results of semi-quantitative analyses confirmed that most of analysed mineral phases conform well to stoichiometric minerals with minor deviations of oxygen from stoichiometric proportions. Comparison between mineral phases in chondrules and interstitial matrix was also performed, however it showed no significant differences in elemental composition. Differences in chemical composition between minerals ininterstitial matrix and chondrules are sometimes too small to be discerned by the SEM/EDS, therefore knowledge of SEM/EDS capabilities is important for correct interpretation of chondrite formation"},{"@xml:lang":"sl","#text":"Cilj študije je bil oceniti možnost uporabe vrstičnega elektronskega mikroskopa z energijsko disperzijsko spektroskopijo rentgenskih žarkov (SEM/EDS) za določitev mineralnih faz po njihovi stehiometriji in oceno mineralne sestave navadnega hondritnega meteorita. Za raziskavo je bil uporabljen navaden hondritni meteorit tipa H3 Abbott. SEM/EDS omogoča prepoznavanje in opredelitev mineralnih faz, katerih velikost je pod ločljivostjo optičnega mikroskopa. Položaj mineralnih faz v hondrulah in medzrnski osnovi je bil določen v načinu povratno sipanih elektronov (BSE). Mineralna sestava je bila ocenjena iz atomskih razmerij sestavnih elementov, pridobljenih z EDS analizo. SEM/EDS analize mineralnih faz so pokazale, da meteorit Abbott sestavljajo (Fe, Ni)-zlitina kamacit, Fe-sulfid troilitoziromapirotin, kromit, Mg-olivin, ortopiroksen broncit ali hipersten, klinopiroksen Al-diopsid, kisli plagioklaz oligoklaz, akcesorni mineral klorapatit in sekundarni minerali Fe-hidroksidi (goethit ali lepidokrokit). Rezultati semi-kvantitativnih analiz so pokazali, da se večina analiziranih mineralnih faz dobro ujema s stehiometričnimi minerali z manjšimi odstopanji kisika od stehiometričnih razmerij. Primerjava med mineralnimi fazami v hondrulah in medzrnski osnovi ni pokazala bistvenih razlik v elementarni sestavi. Razlike v kemični sestavi med minerali v medzrnski osnovi in hondrulah so lahko tako majhne, da jih ni možno ugotoviti s SEM/EDS. Za pravilno interpretacijo nastanka hondrita je zato pomembno poznavanje zmogljivosti SEM/EDS"}],"edm:type":"TEXT","dc:type":[{"@xml:lang":"sl","#text":"znanstveno časopisje"},{"@xml:lang":"en","#text":"journals"},{"@rdf:resource":"http://www.wikidata.org/entity/Q361785"}]},"ore:Aggregation":{"@rdf:about":"http://www.dlib.si/?URN=URN:NBN:SI:doc-6ZFZWSYE","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:doc-6ZFZWSYE"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:doc-6ZFZWSYE/bce2e84e-ae22-4a67-b7ae-523b30764bdf/PDF"},"edm:rights":{"@rdf:resource":"http://creativecommons.org/licenses/by/4.0/"},"edm:provider":"Slovenian National E-content Aggregator","edm:intermediateProvider":{"@xml:lang":"en","#text":"National and University Library of Slovenia"},"edm:dataProvider":{"@xml:lang":"sl","#text":"Geološki zavod Slovenije"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:doc-6ZFZWSYE/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:doc-6ZFZWSYE"}}}}
