Magnetic spherules from Pleistocene terrestrial sediments in southern Hungary were systematically collected and investigated. By means of chemical analysis, Fe, Fe(Mn), Fe(Ni) and glassy (silicate) spherules can be distinguished. Some of them have characteristic features suggesting an extraterrestrial origin: Ni-bearing crust, Ni-rich core and especially the platinum group nuggets with their unique chemical composition. They could have been formed by meteorite ablation process.
