摘要

摘要:
浮游有孔虫表层水种Globigerinoides ruber （白色）和Trilobatus sacculifer壳体是过去海洋环境信息的重要载体，其壳体Sr/Ca比值在重建古海洋环境变化中具有较大潜力，因此本文旨在探讨G. ruber（白色）和T. sacculifer的不同形态类型Sr/Ca比的差异及其影响因素。对取自西菲律宾海的MD06-3047B沉积物岩芯中G. ruber的两种形态类型，即G. ruber（sensu stricto, s.s.）和G. ruber（sensu lato, s.l.），以及T. sacculifer 的两种形态类型，即T. sacculifer （with sac）和T. sacculifer （without sac）壳体的Sr/Ca进行了测试分析。结果显示，MIS 3期（～48 ka）以来，MD06-3047B岩芯中G. ruber s.s.和G. ruber s.l. 的Sr/Ca差异较小；而T. sacculifer （with sac）和T. sacculifer （without sac）的Sr/Ca存在显著差异，且前者显著高于后者。通过与同站位表层海水温度和盐度等记录的对比，发现研究区G.ruber s.s.、G. ruber s.l.和T. sacculifer （without sac）壳体的Sr/Ca可能主要受控于海水温度，而T. sacculifer （with sac）壳体Sr/Ca受到海水盐度的影响。

Abstract:
Surface-dwelling foraminifera species Globigerinoides ruber (white) and Trilobatus sacculifer are the main proxy carriers for past oceanic environments. The Sr/Ca ratios of foraminifera play an important role in reflecting paleo-oceanic environmental changes. To understand the potential differences between the Sr/Ca ratios of these different morphotypes of G. ruber (white) and T. sacculifer and relevant affecting factors, we compared the Sr/Ca measurements of the two basic morphotypes of G. ruber (G. ruber sensu stricto and G. ruber sensu lato) and T. sacculifer (with sac and without sac) via the analysis of surface and downcore samples of sediment from Core MD06-3047B in the Western Philippine Sea. Results reveal that the Sr/Ca ratios of the two morphotypes of G. ruber (white) show a little difference since MIS 3 (～48 ka), while those of two types of T. sacculifer are significantly different from each other, of which that of T. sacculifer (without sac) is generally greater than that of the with-sac type. By comparing the seawater temperature and salinity from the same site, we found that the Sr/Ca ratios of G. ruber s.s., G. ruber s.l. and T. sacculifer (without sac) in our study area might be affected mainly by seawater temperature, and those of T. sacculifer (with sac) are mainly affected by surface salinity.
