MAJOR ELEMENT COMPOSITIONS OF SURFACE SEDIMENTS IN THE EAST PHILIPPINE SEA AND ITS GEOLOGICAL IMPLICATION
-
摘要: 为系统了解东菲律宾海表层黏土沉积物的常量元素组成特征与地质意义,对其在53个样品中的含量及在3个典型样品中的赋存状态进行了综合性分析。结果表明:沉积物中的主要常量元素组分包括SiO2、Al2O3和Fe2O3,它们绝大部分赋存于碎屑成因的残渣态中;沉积物中金属元素锰含量相对附近边缘海为高,且主要赋存于水成成因的铁锰氧化物态中。所研究海区表现出接近于大洋属性的深海沉积环境特点,其物质来源主要为附近火山碎屑物质及火山热液活动,而陆源黏土矿物及生物作用的影响较小。Abstract: To systemically understand the character and geological implication of major element compositions of surface sediments in the East Philippine Sea, integrated analyses of major element contents of 53 samples and elemental occurrence of 3 typical samples have been carried out. The major elements component of SiO2, Al2O3 and Fe2O3 are mainly concentrated in the detrital component. The metallic element (that is, Mn) content is higher in the study area than that in the adjacent marginal seas, with main concentration in the hydrogenic ferromanganese phase. The sediments occur in a deep-sea environment,and are mainly derived from nearby volcanic detritus and volcanic hydrothermal activities, with minor contributions from continental clay minerals and biological materials.
