The research was focused on strewnfield in “Meteorite Morasko” reserve. The main goal of the project was to find correlation between chemical composition of soil and concentration of cosmogenic material which was discovered in the region. After field prospection the sampling was made for three reference regions in the reserve. ICP-MS method was used to determine the elemental composition of soil samples. Investigation has been carried out to indicate the chemical components which iron meteorite matrix is built of like Fe, Ni and Co. Results of the study gave information about distribution and correlation of chemical components in the reserve.

Nondestructive high-resolution gamma spectrometry techniques were used to measure cosmogenic radionuclides in 32.5g fragment of Oslo meteorite which the fall was not observed. Five radioisotopes with half-lives ranging from 278.1 days to 7.17´105 years have been detected. The signals observed for 26Al, 22Na, 54Mn, 57Co and 60Co were interpreted in terms of the meteoroid depth profiles and terrestrial age after the fall. The pre-atmospheric radius of the chondrite was estimated to be >100 cm. Concentrations of short-lived nuclides limits the fall date before December 2011.
