Chilhowee Group

The Chilhowee Group is a sedimentary body composed of early Cambrian siliciclastic sedimentary rocks which crop out along the eastern margin of the Blue Ridge province in Maryland and Virginia. They represent a rift to passive margin sequence, with mostly coarse, feldspathic sandstones and conglomerates in the lower member and shales and phyllite in the upper members.The Chilhowee Group contains four formations; the Loudoun, Weverton, Harpers and Antietam.[1]
