Abstract

Paleoclimate changes are reconstructed from Late Miocene-earliest Pleistocene deep-water sediments of the Solo River section, using fluctuations in planktonic foraminiferal faunas, water depth and clastic influx. Intervals with common cold-water planktonics (Globigerina bulloides, Neogloboquadrina cf. pachyderma) are thought to reflect periods of increased upwelling, triggered by Antarctic glaciations.Correlations with well Bodjonegoro-1 (Java), DSDP Site 62-1 and Lamont Core RC 12–66 (Equatorial Pacific) using planktonic foraminiferal datum levels and paleoclimate trends suggest non-synchroneity of several commonly used datums, probably due to differences in species concepts. It also allowed dating of the climate changes with regard to the magnetostratigraphic and numerical time scales.For correlations between different faunal provinces global climate changes are an extremely useful tool, probably superior to any single faunal datum. Using this, with other evidence, the following correlations could be obtained between the five “climatostratigraphic” zones in the Solo River section and the Mediterranean and New Zealand stages (from bottom to top): 1.Zone I, samples SR 63–SR 53, cool, older than 6.0 m.y. – ±5.8 m.y., magnetostratigraphic Epoch 6 (and older?) — basal Epoch 5, planktonic zone (Upper N16?-) N17, Mediterranean stages (upper?) Tortonian—Early Messinian, New Zealand Stages Tongaporutuan—Early Kapitean, Late Miocene.2.Zone II, SR 52–SR 35, moderately warm with fluctuations, ± 5.8 m.y.–5.0 m.y., Epoch—lowermost Gilbert, upper N17 (−N18?), Late Messinian (evaporite phase), Late Kapitean, Late Miocene.3.Zone III, SR 34–SR 33, cool, 5.0–4.8 m.y., within Lower Gilbert, (N18?-) basal N19, latest Messinian (“Lago Mare” phase), latest Kapitean or earliest Opoitian, latest Miocene.4.Zone IV, SR32–SR 18, warm to very warm, 4.8–±2.7 m.y., within Lower Gilbert — within Upperg Gauss, N19 within N21, Zanclean-Piacenzian, Opoitian Pliocene.5.Zone V, SR17–SR 12, cool, ±2.7 m.y.—age of top unknown, Upper Gauss-Lower Matuyama, within N21 (−N22?), Santernian or basal Calabrian s.l., Waipipian, basal Pleistocene (Late Pliocene of workers with different Pliocene-Pleistocene boundary concepts).
