中文摘要
9506716 Rea将进行一项高分辨率地层学研究,分别根据北太平洋岩心的IRD通量和温度年代学,在轨道和千年时间尺度上确定西伯利亚和阿拉斯加全球条件开始的时间,以及北太平洋边缘大规模上新世火山活动的时间。这两种现象之间的时间关系将决定大规模的火山活动是否导致了上新世末期北半球大规模冰川作用的开始。***
英文摘要
9506716 Rea A high-resolution stratigraphic study will be undertaken to ascertain the timing of the onset of global conditions on Siberia and Alaska and the timing of the massive late Pliocene volcanism on the North Pacific rim on orbital and millennial timescales, based on IRD fluxes and tephrochronology of cores from North Pacific, respectively. The temporal relationship between the two phenomena will determine if the massive volcanic activity was responsible for the onset of large scale glaciation in the Northern Hemisphere at the end of Pliocene. ***
