沉积作用

The sedimentation is the foundation, affecting the basic pattern of the reservoir,and the sedimentary facies zones beneficial to the formation and evolution of the reservoir includes platform edge bank facies, introplatform point beach facies and acclivity sedimentary facies, etc.; the diagenesis is the key factor, determining the pattern and scope of the final distribution of the reservoir and being of great influence on reservoir structure, and the diagenesis of promoting the formation of storage rooms is mainly the dissolution occurred during hypergene stage and burial stage;and the tectonism is the condition of influencing the connectivity among various reservoir bodies and among the storage rooms within a single reservoir body.

该套储层是在4亿年左右的地质历史中，由沉积、成岩和构造作用相互影响而形成的最终成果：其中沉积作用是基础，影响着储层的基本形态，有利于储层形成与演化的沉积相为台地边缘滩、台内点滩和上斜坡等沉积相带；成岩作用是关键，决定了储层的最终分布形态和范围，对储层结构的影响至关重要，促进储集空间形成的成岩作用主要有表生期和埋藏期的溶解作用；构造作用是条件，影响着各储集体之间以及单一储集体内部储集空间的连通情况。

Based on the complexity of the sources for the sediments in the Okinawa Trough, the sequential extraction procedure was applied to the hydrothermal influenced sediments in the core H9 recovered from the middle Okinawa Trough. Five fractions, including exchangeable, bound to carbonates, bound to iron and manganese oxides, bound to organic matter, and residual were acquired. Based on detailed analysis for major, minor and rare earth element compositions, the distributions of the elements in various speciations of the sediments were determined and the controlling mechanism was discussed. The variations of hydrothermal signatures in the core, partitioned from the terrigenous, volcanic and biogenic materials, have been demonstrated and the accumulation rates of some elements were evaluated.

本文针对冲绳海槽多种物源沉积作用混杂的特征，采用顺序淋滤萃取方法对海槽中部受热液活动影响的H9岩芯沉积物进行了分离，将沉积物中分为可交换态、碳酸盐结合态、铁锰氧化物结合态、有机结合态和残渣态五个部分，并对各个结合态中常量、微量和稀土元素组成进行了分析，确定了不同元素在不同结合态中分配的比例，分析了控制不同元素进入沉积物的主要机制。

However, this does not disprove that short changes in intensity or direction of the Kuroshio ever occurred at certain short cooling events. The 10Be minimum during the Younger Dryas event may indicate that the Kuroshio had been once greatly weakened or even terminated in the Okinawa Trough area which could be related to the response of the Pacific Ocean to the Younger Dryas. The 10Be and 9Be in surface sediment show totally different distribution patterns. The 10Be distribution is dominated by the input from Kuroshio and its branch, the Yellow Sea Current, whereas 9Be is mainly influenced by terrestrial input of suspended materials from the Yellow River discharge and deposited in the fine-grain size sediment zone southwest of the island of Jeju. Both 10Be and 9Be distribution patterns are different from anthropogenic pollutants such as heavy metal Pb which is dominantly distributed closely to the coastal areas.

冰期时冲绳海槽北部10Be的沉积通量远远高于太平洋大洋海区，充分反映了黑潮的传送带作用和边缘海的聚焦沉积作用，并表明末次冰期时在千年尺度上黑潮仍流经冲绳海槽，且强度并未减弱。10Be的通量在新仙女木时降到整个岩芯所跨时期的最低点，甚至低于10Be的现代大气平均生产率，因此推测在新仙女木事件时，黑潮的变动特别大，有可能改向或断流。
