Light-brown marine type oil shale of Ordovician age
Outcrop of Ordovician kukersite oil shale, northern Estonia
Kukersite is a light-brown marine type oil shale of Ordovician age. It is found in the Baltic Oil Shale Basin in Estonia and North-West Russia . It is of the lowest Upper Ordovician formation, formed some 460 million years ago.[ 1] It was named after the German name of the Kukruse Manor in the north-east of Estonia by the Russian paleobotanist Mikhail Zalessky in 1917.[ 2] [ 1] [ 3] Some minor kukersite resources occur in sedimentary basins of Michigan, Illinois, Wisconsin, North Dakota, and Oklahoma in North America and in the Amadeus and Canning basins of Australia.[ 4]
