The Tenmile Formation is a geologic formation in Oregon. It is part of the Eocene sedimentary succession of the Tyee Basin. Organic matter in these rocks is generally low in abundance and predominantly derived from land plants, producing gas-prone kerogen. The strata are also thermally immature and have not generated significant hydrocarbons.[1]
