    Ancient Proterozoic Precambrian rocks over billion years old form the core of the Rocky Mountains through Colorado. The mountain core is formed of schists and geneisses which were originally comprised of mainly sedimentary (shale, siltstone and sandstone) and some earlier volcanic materials. Precambrian rocks are well exposed in the Rocky Mountains, where to billion-year-old metamorphosed volcanic and sedimentary rocks represent the accretion of an ancient terrane to this portion of the North American continent.

They are made up of many small mountains, called the " spine " of North America. The main mountains are from the British Columbia of Canada to the southwestern United States.

It was not until 80 Ma these effects began reaching the Rockies. The current Rocky Mountains arose in the Laramide orogeny from between 80 and 55 Coordinates: 39°07′04″N °26′43″W / °N. The Rocky Mountain region provides a natural laboratory for study of the fault system because of abundant exposures of exhumed basement rocks and structural features as well as neofaults formed during reactivation.

More mountain building and deep erosion Many features of the present-day landscape of Yellowstone stem from Pliocene time, about 10 million years ago. At that time the entire region—in fact, much of the Rocky Mountain chain—was being uplifted by giant earth movements to heights several thousand feet above its previous level.

Francis Mountains of Missouri, in the Arbuckle and Wichita Mountains of Oklahoma, and form the Plano Uplift of central Texas. The Northern Rocky Mountains include ranges in western Montana (north of Yellowstone National Park) and extending northward into Alberta, Canada (Figure ).The region was impacted by both the Sevier and Laramide Orogenies.

The Lewis Mountains in northern Montana started forming about million years ago as a great slab of sedimentary rocks of Precambrian age (about 3 miles thick) was. Recently compiled aeromagnetic data greatly enhance our understanding of the Precambrian basement from the Rocky Mountain region by providing a means to (1) extrapolate known geology exposed in.The oldest rocks in Montana are part of the Archean Wyoming Craton in the center and east of the state, primarily between Livingston and Red Lodge, as well as small areas in the Little Belt Mountains around Neihart and the core of the Little Rocky Mountains south of Harlem.

Drill cores indicate that these rocks underlie much of the Great Plains.Abstract Recently compiled aeromagnetic data greatly enhance our understanding of the Precambrian basement from the Rocky Mountain region by providing a means to (1) extrapolate known geology exposed in generally widely separated uplifts into broad covered areas, and (2) delineate large-scale structural features that are not readily discernable solely from outcrop mapping.
