Geographic resolution:local area
Time
Period: Silurian Epoch: Pridoli

Stratigraphy
Formation:Camelford
Stratigraphic resolution:formation
Stratigraphy comments: Brachiopods suggest Pridoli age, as does some of the conodont data. Age coincides with that of Camelford Limestone near Wellington, based on conodonts found in that formation.
Lithology and environment
Primary lithology:gray grainstone
Lithology description: "Massive limestones contrasting in lithologies and faunas with the Garra outcrop E of the Eurimbla Fault. The lower part of this unit consists of coarse crinoidal calcarenites with interbeds of limestone conglomerates. The remainder of the unit is dominated by massive limestone conglomerates with a distinctive reddish or pinkish dolomitic matrix, although grey colourations are also present. Subordinate lithologies with the upper part of the formation include massive dove-grey to dark grey calcisiltites and calcilutites as well as what may be non-carbonate unites...Limestones near the base of the formation include silicified stromatoporoids [etc.]"
Environment:marine indet.
Geology comments: See lithology.
