%X The formal stratigraphy of Late-Quaternary late- and post-glacial sediments in the Archipelago Sea, northern Baltic Sea, is revised. The Trollsk r Allomember and Sand n Allomember were previously incorrectly defined as allostratigraphic units based on an acousticdiscontinuity, even though their contact is gradational in the studied sediment cores. These allostratigraphic units are formally redefined herein as the lithostratigraphic units Trollsk r Formation and Sand n Formation, which belong to the Korppoo Alloformation.The purpose is to forestall misconceptions concerning temporal relationships and depositional processes at the transition of these two units.
