Time of fall and some properties of the Morasko meteorite

The time of fall of a meteorite and the appearance of the impact craters in Morasko have been documented by the thermoluminescene method, 14C dating, as well as palynological estimation. The extraterrestrial effect on the lithology and morphology of Moraska Góra (Morasko Hill) took place about 5000 years BP. Morasko meteorite is composed in about 98 wt. % of Fe--Ni alloy and in about 2 wt. % of dark FeS nodules, up to 20 mm in diameter. The principal Fe--Ni alloy is kamacite with nearly 6% Ni and taenite with up to 30% of Ni. FeS occurs as troilite, being often wrapped up by rounded flakes of graphite.
