An undersea complex meteorite impact crater approximately 20km in diameter.
Located in the Gulf of Finland.

At the moment of the impact about 150 m of unconsolidated or weakly lithified siliciclastic deposits covered the Precambrian metamorphic rocks. Presently the compacted ca. 100 m thick pre–impact succession is composed by Fortunian (Lower Cambrian) sandstones, siltstones and clays of the Lontova Fm. (ca. 40 m) on the top of a complex of Neoproterozoic Ediacaran weakly lithified quartzose sandstones (about 60 m). In the Palaeoproterozoic (Orosirian) Svecofennian basement strongly folded migmatite granites, gneisses and amphibolites dominate. The basement is covered by a 5–10 m thick illite–rich weathered crust.
