摘要: summary Pollen and plant macrofossils from Langdon liner give an interglacial floral record for western Tasmania. The location of the site between ice limits Last or Margaret Glaciation Penultimate Henty indicate that it cannot be younger than Interglacial. sequence vegetation changes shows succession Casuarina Phyllocladus-Nothofagus with as pioneer Nothofagus representing Maximum wet forest development. After maximum presence Phyllocladus-Nothofagus-Eucalyptus-Microstrobos suggests deterioration to subalpine woodland/shrubland, Compositae, Gramineae-Microstrobos alpine shrubland herbland. represents most a glacial-interglacial-glacial cycle Of environmental occurred before 43 000 14C yr B.P. Very high values occur in early part at which contrasts Holocene where Eucalyptus is more important Casuarina. Otherwise Phyllocladus, Nothofagus, Eucryphia-Anodopetalum same interglaeial ‘optimum’ marked by occurrence Pomaderris apetala type Dicksonia antarctica. There some similarity curves Lake George interglacials But, on whole, there rainforest development South Island, New Zealand Only one change recognized River unlike central Chilean records 40-42° S different ways mid Interglacial climatic deterioration.
