Over 180 diatom taxa were identified in the borehole core. Most of the horizons analyzed were characterized by fresh water species, and their environments were inferred as marshes, bogs and small ponds. Several minor transgression events were also recognized for the past 5000 yrs.}, pages = {57--62}, title = {珪藻遺骸からみた越後平野升潟地域における上部完新銃の古環境変遷}, volume = {24}, year = {2002} }
