摘要

我们比较了印度洋和大西洋主要类型的更新世沉积物的算术平均化学成分，以及两大洋更新世的平均化学成分。作为比较的基础，我们使用了国际深海钻探项目报告（DSDP、ODP、IODP 阶段）和其他参考资料中的数据。结果表明，平均加权化学成分的比较分析结果是由干沉积物的质量决定的。大西洋的质量累积率高于印度洋的质量累积率，其原因是集水区明显更大、受更显著的潮湿气候影响以及初级生产增强。

Comparative Analysis of Geochemical Peculiarities of Pleistocene Sediments in the Indian and Atlantic Oceans

We compared the arithmetic average chemical composition of main types of Pleistocene sediments in the Indian and Atlantic oceans, and average chemical composition of the Pleistocene in both oceans as well. As the base for comparison, we used data from the International project of deep-sea drilling reports (phases DSDP, ODP, IODP) and other references. It was revealed that the results of comparative analyses of the mean weighted chemical composition were determined by masses of the dry sediment matter. Domination of the Atlantic mass accumulation rates over the Indian Ocean ones was due to markedly larger catchment areas, influence of more significant humid climate, and enhanced primary production.

期刊介绍： Lithology and Mineral Resources is an international peer reviewed journal that publishes articles on a wide range of problems related to the formation of sedimentary rocks and ores. Special attention is given to comparison of ancient sedimentary rock and ore formation with present-day processes. The major part of the journal is devoted to comparative analysis of sedimentary processes on the continents and in oceans, as well as the genetic aspects of the formation of sedimentary and hydrothermal–sedimentary mineral resources. The journal welcomes manuscripts from all countries in the English or Russian language.
