Lake Suigetsu ('Suigetsu-ko') is a tectonic lake, situated close to the Sea of Japan coast at Wakasa Bay, Honshu Island, central Japan. > max. resolution

The upper ~46 m of the Lake Suigetsu sediment profile demonstrates distinct lamination and represents sediment deposition spanning approximately the last 60,000 years. > max. resolution

The varves are composed of alternating layers of diatom-rich sediment and Mn-enriched siderite [(Fe,Mn)CO3] deposited predominantly after lake overturn in autumn. > max. resolution
