Consists of interbedded limestone, dolomitic limestone, calcareous shale, calcareous dolomite, and dolomite. Limestone and dolomitic limestone beds are dark-gray to medium-dark-gray, very fine-grained to medium-grained, and argillaceous, and weather medium-gray. Calcareous shale is medium-dark-gray, weathers medium-gray, and contains desiccation cracks. Dolomite and calcareous dolomite are medium-gray, very fine-grained, argillaceous, flaggy to massive, laminated, and pyritic, and weather yellowish-gray. Member present in New Jersey, New York, and Pennsylvania. At type section is 22.5 feet thick. Near Port Jervis, northeast of type section, thickens to 56.9 feet at Cuddebackville, New York. Thins to 11.5 feet at Minisink Hills, Pennsylvania. Both upper and lower contacts are abrupt. Underlies Whiteport Dolomite Member. Overlies Clove Brook Member (new) of Decker Formation and in some areas Wallpack Center Member (new) of the Decker. Contains ostracodes, fragmented corals, stromatoporoids, bryozoans, and as noted by Weller (New Jersey Geol. Survey Rpt. on Paleo., v. 3, 1903) brachiopods, pelecypods, and one gastropod. Age is Late Silurian or Early Devonian. Report includes measured sections. (Duttonville Member of Rondout Formation of Helderberg Group adopted by the USGS.)
Type section: in the abandoned William Nearpass quarry, 1.8 mi southwest of Duttonville, and 0.5 mi due west of Clove School, in northwest quarter of Port Jervis South 7.5-min quadrangle [approx.
