马里亚纳海槽区岩芯中浮游有孔虫和CaCO_3溶解及其影响溶解的因素

The Features of Planktonic Foraminifera and CaCO_3 and Their Dissolution and Controlling Factors in the Cores of the Mariana Trough

本文从浮游有孔虫壳体保存,数量,分异度值,底栖类/浮游类比率和CaCO_3含量诸方面讨论马里亚纳海槽区岩芯中溶解及其影响溶解的因素。

The dissolution of planktonic Foraminifera and CaCO_3 and their controlling factors in the cores of the Mariana Trough were discussed based on the preservation and the total number of pianktonic Foraminifera shells, the value of diversity H(S), the benthon/plankton ratio and the CaCO_3 content.
