厦门港湾表层沉积物中Fe_2O_3,Al_2O_3,TiO_2含量的分布及相关性

DISTRIBUTION OF CONTENTS OF Fe_2O_3, Al_2O_3 AND Ti_2O AND ITS RELATIONSHIP TO SURFACE SEDIMENTS IN THE XIAMEN HARBOUR

据国家海洋局第三海洋研究所1980—1981年厦门港湾环境综合调查资料,报道了该港湾表层沉积物中Fe_2O_3,Al_2O_3和TiO_2含量的分布,讨论了它们之间及其与沉积类型的关系。

Distribution of concents of Fe2O3,Al2O3 and TiO2,and their relationship to sediment types in surface sediments in the Xiamen Harbour are reported based on the data of 219 samples collected during the comprehensive environment survey in the area from 1980 to 1981.The results show that content variation range and average of Fe2O3 are 0.67—10.7 and 4.73%;Al2O3,3,59—21.9 and 13.3%)TiO2,ND—0.99 and 0.59 respectively in surface sediments in the Harbour.Distribution of contents of the studied substances has been considered to be mainly controlled by hydrodynamics and sediment types(contents increase with sediment fineness),and there is an obvious Positive interrelation among their contents in the sediments,which may concern with their identical sources.
