Holocene sediments of the Kuril Archipelago lakes (Pernatoye, Paramushir Island; Tokatan, Urup Island; Maloye and Kasatka, Iturup Island) were studied. The sediments consist of freshwater lake, lagoon, and marine facies. Pyrite is most often found in sediments of lagoon and marine facies, being their indicator. It is found as separate spheroids and clusters of framboidal structure. Pyrite aggregates fill up diatom valves. Valves were filled with pyrite gradually.
