- 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.
