Opis:: The results of two independent Mössbauer measurements of the same sample of the Pultusk meteorite are discussed. The measurements were performed at room temperature in standard conditions (256 channels) and with higher resolution (1024 channels). Very small differences in the percentage of the spectral areas of all mineralogical phases present in Mössbauer spectrum (olivine, pyroxene, metallic phases, troilite and ferric iron) convince that the measurement performed at standard conditions (256 channels) are sufficient for correct determination of the mineralogical composition of the investigated sample.

Opis:: On 21 of July 2001, small fragment of metal has been found on side walk, near branch of Silesian University in Cieszyn, by Ms. Małgorzata Kotowiecki. After a few years, the metallic fragment was carefully study. The investigation show that the metallic element has meteoritic origin. The mineral composition of the meteorite (kamacite, taenite, tetraenite, troilite, daubreelite) classify it as an iron meteorite and the most probably is representative of octahedrite. The meteorite has features of shock metamorphism and represent very old fall. It could be supposed that the meteorite has been transported to the destination place, together with gravel.

Opis:: Fossil iron meteorites are extremely rare in the geological sedimentary record. In the boundary clay from the outcrop at the Lechówka quarry (Poland), fragments of the paleometeorite were found in the Cretaceous-Paleogene boundary clay layer. The fragments of meteorite (2–6 mm in size) and meteoritic dust are metallic-grey in colour. Analyses of the meteorite from Lechówka reveal the presence of Ni-rich minerals with a total Ni amount of 2–3 wt%. They are represented by: taenite, kamacite, schreibersite, Ni-rich magnetite, and Ni-rich goethite. The investigated remnants of paleometeorite apparently represent an independent fall and does not seem to be derived from the K-Pg impactor.
