Primary lithology:concretionary,green,red carbonaceous mudstone
Secondary lithology:"cross stratification",medium,coarse,white,yellow conglomeratic sandstone
Includes fossils?Y
Lithology description: Bones found in two facies: "1) trough cross stratified sandstones; and 2) red mudstones. Facies 1 is composed of pale yellow to whitish conglomeratic sandstones and sandstones that vary in thickness from 2 to 4 m. The conglomerates grade upward into coarse sandstones. Fine grained, medium bedded, lithic conglomerates and medium to coarse grained lithic sandstones are present. The trough cross bedding is well developed and bet set thicknesses vary from 0.30 to 0.10 m...Facies 2 is composed mainly of thinly bedded red and green mudstones; carbonate nodules are common."
Geology comments: Facies 1: channel-fill deposits; facies 2: floodplain deposits; both within a meadering river system.
