Abstract

The high-resolution content sequences aboutiron,manganese,ratios of iron to manganese,CaCO₃ and acetic acid-soluble magnesium in the SZ2 column from the northeast continental slope of the South China Sea have been set up.There are remarkable positive correlations among iron,manganese and CaCO₃ and negative correlations between CaCO₃ and the ratios of iron to manganese.The positive correlat ions between iron and manganese show that their content changes on the vertical are identical.The depth of redox boundary of iron is deeper than that of manganese.In the process of diagenesis,the original content of iron has been kept in the deposit column,and the content of manganese kept in the column is much less than its original content,however,the content of manganese in the column is enriched during glacial era.It is concluded that the changes of manganese content reveal the strong fluctuation of sea productivity,deposit rate and temperature,and the fluctuation of the concentration of iron reveals the fluctuation strength and frequency of global clmiate and supply of iron from the continent.The changes of concentration of manganese in the column are abrupt,which often happen in the depth where there are the turning points of content changes of CaCO₃.The ratios of iron to manganese in the glacialera are less than those of interglacial.The ratios of iron to manganese are an miportant and sensitive proxy indicators for the deposit rate,and for the changes of CaCO₃ in the column,and for the changes of CO₂ in the atmosphere
