    The Earliest Oligocene Glacial Maxmum: Records from ODP Site 1265, South Atlantic

    • 摘要: 始新世—渐新世(EO) 过渡期间, 地球由两极无冰的“温室地球”进入到南极有冰的“冰室地球”, 其中以发生在早渐新世初的大冰期事件尤为意义重大.南大西洋ODP1265站氧碳稳定同位素在EO过渡期间发生重大变化, 表明早渐新世全球气温迅速下降, 南极大陆东部首次出现大规模永久性冰盖, 同时全球碳储库发生重大改组, 这一结果与全球其他地区的记录一致.碳酸盐含量、粗组分、浮游有孔虫碎壳率以及碳酸钙软泥的粒度在EO界线附近都发生了突变, 指示了海洋表层生产力的升高、碳酸盐补偿深度(CCD) 的突然加深以及气候快速变冷对生物和碳酸盐沉积的影响.
