摘要
众多学者用不同方法对已知的长江和黄河沉积物进行了分析比较,以期获得区分两者的有效指标。由于两河物源区物质成分的差异和所处气候带不同造成的后期风化的不同,其沉积物在化学元素和矿物组成等方面存在较大的差别。但是运用这些差别来判识陆架海区物质来源的问题则复杂得多,目前仍处在不断探索之中。通过对这些资料的归纳总结,提出应尽量运用多个指标进行物源判识。
Different methods have been used to compare the Changjiang River sediment with the Yellow River sediment to get the effective indicators for distinguishing between the two sediments. The differences in source area and climatic zone of the two sediments result in the differences in their chemical element and mineral compositions, but it is quite difficult to use these differences to discriminate the material sources in the shelf sea area. Based on the synthetic analysis results of the two sediment data, it is suggested to use several indicators to discriminate the material sources of the sediments in the East China Sea shelf area.
