Description
According to the previous seller, “This is one pound of oil shale collected outside the Unocal (Union Oil of California) site and consists of two pieces. The site has been abandoned for many years, North of Parachute, Colorado. Oil shale is a misnomer and is best described as a marlstone. This shale sample contains at least 10 gallons of oil, per ton of material. The site is on the Piceance Basin, which is one of the largest oil shale deposits in the world. Oil shale yields olefins and parafins, which upon distillation yields an oily material known as kerogen. The kerogen was derived essentially from plant material. When oil shale is heated with a torch, the kerogen will burn.”
