沉积 [地] deposit; sedimentation; deposition; precipitation 陆相沉积 continental deposit; 海相沉积 marine deposit; 河口沉积了淤泥。 the river deposited silt at its mouth. 尼罗河泛滥时, 在田野上沉积下一层泥。 when the nile is in flood, it deposits a layer of mud on the fields
Secondly , granularity analysis of sediments of upper marine facies of holocene is done 其次,对全新世海相层及其以上地层中的沉积物进行粒度分析,划分垂向沉积序列。
Based on the deposital velocity of the magnetic strata unit , the paper has worked out the velocity of the genetic unit of the basin utilizing the vertically evolutive map 以磁性地层单元内的沉积速率为基础,结合静43 - 67井的垂向沉积相演化图,计算出断陷湖盆成因相的沉积速率。
Many bore holes in shuangwangcheng reservoir which lies in the sedimentary area are drilled and lots of terra drill data are collected . five typical sections , i . e . section i ? i , ii ? i , iii ? ii , iv ? v ' and v ? v are drawn . the vertical sedimentary sequence of this sedimentary area is divided cbmbining the granularity features of sediments 课题组与山东省水利勘测设计院合作,对湖区内的双王城水库进行了钻探研究,搜集了大量的地质钻孔资料,经沉积物岩性特征分析,绘制出双王城水库外围1km处围绕水库的5个典型剖面(即剖面? ’ 、 ? ’ 、 ? ’ 、一’和? ’ )的剖面图,结合沉积物粒度特征,划分出该沉积区的垂向沉积序列。
