Deposit of Y- and HREE-enriched brown coals.
Eluvial sediments overlying kaolinitized Lower Cambrian schists. The schist was intruded by hydrothermally altered basic (alkaline basaltoid) extrusive dikes, thought to be Pliocene–Quaternary, that may have generated or activated saline hydrothermal fluids during intrusion and the accompanying extrusion of basalts.
Located between Osimovka and Abramovka Rivers.
