摘要
本文依托菲律宾海浅地层剖面资料,结合前人已发表的该区域样品资料和钻孔资料,对九州-帕劳海脊以及与海脊相邻的西菲律宾海盆和帕里西维拉海盆浅层沉积物特征进行了初步研究。研究认为海底以下浅层沉积物一般存在3个波阻抗界面,根据其反射特征划分为4个基本类型,并对剖面特征的成因进行了初步探讨,认为在沉积物的沉积过程中,沉积物供给、构造活动、地形以及水动力条件等都对深水沉积起到了重要的作用。本文通过对菲律宾海浅地层沉积特征和控制因素的分析,可为进一步开展菲律宾海深水浅层沉积物研究提供参考。
Based on the data of Philippine shallow strata profile, combined with the sample data and borehole data in this area, this paper has a preliminary understanding of the shallow sediment characteristics of Kyushu-Palau Ridge and the West Philippine Basin and Parisi Vera Basin adjacent to the ridge. There are generally three wave impedance interfaces below the seabed, and the reflection characteristics of the shallow stratum profile are divided into four basic types. The causes of the profile characteristics are preliminarily discussed. It is believed that the sediment supply, tectonic activities, topography and hydrodynamic conditions play an important role in the deep-water sedimentation during the sedimentation process. Besides being influenced by the main control factors, most of them are also superimposed with the transformation effects of various factors in the later period. In this paper, the sedimentary characteristics and controlling factors of shallow strata in Philippine Sea are analyzed, which can provide useful reference for further study of deep shallow sediments in Philippine Sea.
