They range in age from Cambrian to Tertiary and were formed in The Niobrara Shale is a shale rock formation located in Northeast Colorado, Northwest Kansas, Southwest Nebraska, and Southeast Wyoming. Oil as well as natural gas can be found deep below the earth's surface at depths of 3,000 - 14,000 feet. Fracking is used to extract these natural resources.Shale outcrop from the northern Norway. Hammer for scale. Mud covering a dry riverbed in La Palma, the Canary Islands. The main ingredient of shale is clay which is here on the way from the disintegrated rock higher in the mountains to the sea where it will be finally deposited. Rivers do the hard job of carrying all the mud to the ocean. Oil shale deposited in small lakes, bogs, and lagoons is found associated with coal seams. Deposits of this type occur in a sequence found in western Europe dating from the Permian Period and in deposits of northeastern China laid down in the early Cenozoic Era .Oil shale is a sedimentary rock. As it reaches its oil window, oil shale releases a liquid known as shale oil. Oil shale is the rock from which shale oil is extracted. Shale oil is similar to petroleum, and can be refined into many different substances, including diesel fuel, gasoline, and liquid petroleum gas ( LPG ).The Bright Angel Shale consists of locally fossiliferous, green and red-brown, micaceous, fissile shale (mudstone) and siltstone with local, thicker beds of brown to tan sandstone and limestone. It ranges in thickness from 57 to 450 feet (17 to 137 m).
