Abstract. Uncommon geological section revealed and described on the southern-western slope of Izhorskoe plateau near St. Petersburg. Crushed but not displaced plates and boulders of Ordovician calcite dolomite, filled by Quaternary marine sands. Ordovician trilobites and brachiopods from dolomites determinated. Samples for dating and determination of Quaternary sedimentary environments collected.

Keywords: Quaternary marine sands, Ordovician dolomites, Izhorskoe plateau
