| 摘 要： | 为探讨沉积物粒度与水合物饱和度的关系,对南海神狐海域水合物钻探区2个获取水合物的钻孔岩心沉积物进行了粒度分析及粒度与水合物饱和度对比分析.结果表明,含水合物沉积物具有粉砂含量72％～82％、黏土含量小于30％、砂含量一般小于10％的基本特征,其中粉砂中以8～32和32～63 μm粒级的中细一粗粉砂占优势；该特征与上下不...

| Abstract: | Grain sizes are analyzed for the sediments taken from two drill holes in the Shenhu area of northern South China Sea in order to understand the relationship between the saturations of gas hydrates and the grain-size of the sediments.Results suggest that the silt fraction is the dominant component of gas-hydrate-bearing sediments in the studied area,making up about 72%~82% of the sedimentary grains.The second component is clay,which is usually less than 30%;whereas the sand fraction is less than 10%.The Grai... |
