 note = {An analysis of remanent magnetism and radiocarbon ages in the dry lacustrine/sediment fills of the Schirmacher Oasis (SO) in East Antarctica was conducted to reconstruct past climatic condition. The statistically run mineral magnetic data on paleontological statistics software package (multivariate cluster analysis) placed on accelerator mass spectrometer radiocarbon chronology of the three sediment sections, trace 6 phases of climatic fluctuation between 13 and 3 ka, (Phases 1, 3 and 5 represent cold periods while Phases 2, 4, and 6 represent warm periods). One short warm period (Phase 2, ca. 12.5 ka) occurred in the late Pleistocene, and two marked warm periods (Phase 4, 11–8.7 ka; Phase 6, 4.4–3 ka) occurred in the Holocene. High magnetic susceptibility (χ), saturation isothermal remanent magnetism (SIRM), and soft isothermal remanent magnetism (soft IRM) values correspond to colder periods and low values reflect comparatively warmer lacustrine phases. Holocene Optima (Phase 4) and Mid Holocene Hypsithermal (Phase 6) are distinguished by decreased values of concentrations dependent parameters. Remanence is preserved in the low-coercive minerals. Heavy metals in the sediments include, Fe, Rb, Zn, Mo, Co, Pb, Mn, Cu, and As in order of decreasing abundance., 東南極・Schirmacher Oasis (SO)の乾燥した湖底堆積物の残留磁化と放射性炭素年代の解析を行い、過去の気候条件復元を試みた。13から3kaに渡る3つの堆積層序において６つの気候変動相 (Phase 1–6) が認められ、Phase 1, 3, 5が寒冷期、Phase 2, 4, 6が温暖期に相当する。約12.5 kaの短いPhase 2は更新世後期にあたり、Phase 4 (11–8.7 ka)とPhase 6 (4.4 – 3 ka)は完新世に当たる。磁化率（χ）、飽和等温残留磁化（SIRM）、及び等温残留磁化の低保磁力成分（soft IRM）が高い値の時は寒冷期に、逆に低い時は温暖期に当たっている。Holocene Optima (Phase 4)とMid Holocene Hypsithermal (Phase 6)は磁性鉱物量依存パラメターの示す値が減少することで区別できる。},
