The elemental geochemistry characteristics indicate that elements abundance is controlled seriously by grain size of sediment. 元素地球化學(xué)特征表明，元素的豐度受沉積物粒度控制明顯。
Study also shows that element geochemical method is useful in provenance discrimination, because it can effectively avoid the influence of hydraulic sorting. 分析表明元素地球化學(xué)方法在沈積物物源判別時(shí)，可有效的避免水動(dòng)力因素影響，取得較好的效果。
