Abstract
The formal stratigraphy of Late-Quaternary late- and post-glacial sediments in the Archipelago Sea, northern Baltic Sea, is revised. The Trollskar Allomember and Sandon Allomember were previously incorrectly defined as allostratigraphic units based on an acoustic discontinuity, even though their contact is gradational in the studied sediment cores. These allostratigraphic units are formally redefined herein as the lithostratigraphic units Trollskar Formation and Sandon 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.
