海底沉积物的系统研究始于1872—1876年英国《挑战者》号的调查.第二次世界大战后许多国家都大力发展了深海调查.但到1968年深海钻探计划实施前,人们仍主要局限于松散沉积物的调查.本文论述的西太平洋海区是指东起夏威夷,西至亚洲大陆,南达新西兰和澳大利亚,北到白令海峡的广大海区(图1).底质的分布及其分类,主要是根据美国拉蒙特-多尔蒂地质调查所和我国的有关资料综合分析研究后完成的.本区沉积物按其物质来源大致可分为陆源的、生物的和多源的三大类.
Systematic studies of seabed sediments began with the investigation of the British “Challenger” in 1872-1876, and many countries under the World War II developed deep-sea surveys, but until the deep-sea drilling program of 1968 was implemented the main limitation Survey of Loose Sediments. The Western Pacific Ocean area discussed in this paper refers to the vast sea area (Figure 1) starting from Hawaii to the west, to the continent of Asia, to New Zealand and Australia to the south, and to the Bering Strait to the north (Figure 1). The Distribution and Classification of Sediments , Mainly based on the comprehensive analysis and research of the United States Lamont-Doherty Geological Survey and relevant data in our country.The sediments in this area can be roughly divided into three categories of terrestrial, biological and multi-source according to their material sources .
