Abstract
The results of the search for tracks of heavy and superheavy nuclei of galactic cosmic rays in the charge range Z = 26 − 129, identified in olivine crystals from Maryalahti and Eagle Station meteorites are presented. The database including characteristics of 21743 tracks, obtained in the OLIMPIA experiment, is currently the largest one within the charge range under study. It includes three tracks of superheavy nuclei with charge 119−6+10 and a minimum lifetime estimated as several tens of years, which can be considered as a direct experimental validation of the existence of natural superheavy nuclei from the “stability island”.
