Abstract:
An unknown meteorite found in South Africa which now is part of geoarchaeological collection of the Romanian Academy of Sciences (RAS) by Prof. Gruia’s courtesy was analyzed for determination of elemental content. Several slices of meteorite via energy-dispersive X-ray Fluorescence analysis (EDXRF) to perform the initial characterization of the olivine aggregates, chondrules, inclusions, matrix and clasts across the surface were analyzed. By using the Amptek’s XRF Kit based on SDD/cadmium telluride (Cd-Te) detectors we analyzed 17 elemental constituents in the sample. The natural radioactive composition of the meteorite sample was measured by using an AHPGe high-resolution gamma-spectrometer. The background gamma radiation spectrum was substracted from the measured gamma ray spectra. The activities of the found natural radionuclides were calculated based on the corresponding gamma energy lines.
