| 摘 要： | 有孔虫壳体Mg/Ca温度计是近10年来发展最快、应用最广的恢复古海水温度的方法之一。随着研究的深入,这一方法面临的问题也越来越突出。其中,海水盐度影响壳体对Mg元素的吸收,是对Mg/Ca温度计＂忠诚度＂最具威胁性、也是近来最受人们关注的因素之一。查阅了最近2年有关Mg/Ca温度计中盐度效应的最新研究成果,整理出对盐度因...

| Abstract: | Mg/Ca-thermometer is one of the most rapidly developed and as well widely used tools to reconstruct paleo-seawater temperatures in the last decade.There is,however,a growing body of evidence showing that the thermometer is significantly biased by a variety of factors.Of them,salinity effect on Mg uptake into biogenic shell calcites is most recently highlighted,with intensive discussions on the fidelity of the Mg/Ca-thermometer in reconstructing paleo-seawater temperature,and in turn in calculating salinity ... |
