中－晚第四纪东太平洋隆起区（南纬２１°）古海洋条件Ｅ．Ｂ．等本文根据微古和氧同位素资料对东太平洋海隆２１°区中－上第四系含金属碳酸盐沉积物进行了详细的气候地层划分，计算了平均沉积速率，恢复了表层水温的变化；并根据最敏感的指示剂——有孔虫碎屑含量计算了...
Middle - Late Quaternary Eastern Pacific uplift (latitude 21 °) Paleocean conditions. B. In this paper, based on the microfoost and oxygen isotope data, the detailed climatic stratigraphy is divided into the middle and upper Quaternary metallogentic carbonate sediments in the 21 ° Hilong area of the eastern Pacific Ocean. The average sedimentation rate is calculated and the change of surface water temperature is restored. And according to the most sensitive indicator - foraminiferal debris content calculated ...
