Summary:

Named the Parrott formation for Parrott, Pulaski Co., southwestern VA. Used for succession overlying the reddish-brown sandstones of the "Chemung" or Broadford sandstone and underlying "jelly-bean" quartz pebble conglomerates at base of Price formation. Consists chiefly of rusty-weathering sandstones and siltstones many of which contain abundant marine fossils. Thickness is 350 to 600 feet. These beds have been included in Price formation.
