Melaleuca Inlet (Pleistocene of Australia)

Where: Tasmania, Australia (43.5° S, 146.1° E: paleocoordinates 43.5° S, 146.1° E)

• coordinate estimated from map

When: Late/Upper Pleistocene (0.1 - 0.0 Ma)

• Coniferous wood form the lens containing leaves has been 14C dated at 38800 +- 1300 B.P (S.U.A 5038). Part of a fossil Banksia infructescence has been dated at 34000 +- 500 B.P (S.U.A. 2947). Colhoun (1986) showed that older 14C dates from western Tasmania can significantly underestimate the age of the deposits due to contamination by younger organic material present in soil water. 14C ages should therefore be treated as minimum ages. Palynological evidence from the lens that contained the leaves is consistent with an interstadial climate possibly from the last glaciation (M.K. Macphail pers. comm.). The Melaleuca Inlet deposit is therefore at least 34000 years old and probably from an interstadial period of the last or second last glaciation. (Jordan et al.1991)

Environment/lithology: terrestrial; lithology not reported

• Leaves of Jordan et. al., 1991 were derived form a single sedimentary lens and the infructescences from a separate lens nerby (C.D. King, pers. comm.). The sediments are composed of large, water-rounded quartz and schist fragments and are probably derived from a high-energy river system.
