Price Neck Formation, first used by Murray and Skehan (1979: International Geological Correlation Program Project 27), was named by M.J. Webster (1983) in a Senior thesis at Boston College. Unit occurs in vicinity of Newport, southeastern RI. Composed predominantly of thin-bedded distal turbidites. Described as graded beds of sandstone, siltstone, and slate with bedded carbonate and volcanic conglomerate, mudflow deposits, ash-flow deposits, and lapilli tuffs. Slates are light green to dark purple where weathered. Sandstone beds are light gray to bluish white. Age is Late Proterozoic (800-700 Ma?) based on intrusion by Cliff Walk Granite (new name) at approximately 595 Ma. Estimated thickness is 900 m. . [This is first published formal definition of unit and is considered to be the formal proposal by the Geologic Names Unit.]
