超层序 meaning in English
supersequence
Examples
- A middle good - quality reservior cycle is a fourth - sequence , and a short cycle is a fifth - sequence . based on it , we subdivide the third member of shehejie formation into 3 third - sequences and 12 fourth - sequences
根据这一旋回划分原则,将研究区沙三段从下到上分成3个三级层序(超层序) , 12个四级层序。 - Through analysis of key - seismic - profiles , it can be divided into 4 seismic sequences from lulehe formation to upper ganchaigou formation , which probably equal to supersequences . in the same time , seismic stratigraphic framework was also established
从骨干地震剖面的层序地层分析可知,区内从路乐河组到上干柴沟组可以划分出4个地震层序,相当于超层序,并建立了地震层序地层格架。 - On the basis of the characteristics of sequence stratigraphy of the cenozoic in puwei sag , dongpu depression , the sequence stratigraphic framework of the cenozoic is set up , including two supersequence sets which is fault depression filling supersequence sets of the eocene , and depression filling supersequence sets of the tertiary
根据东濮凹陷濮卫洼陷新生界层序地层的发育特征,建立了濮卫洼陷新生界层序地层格架,将濮卫洼陷新生界概括为一个盆地充填序列,包括古近系凹陷充填超层序组和新近系坳陷充填超层序组。 - Besides , the sedimentary facies of upper ganchaigou and lower ganchaigou formation were also mapped in supersequences which are the main target strata for exploration . the high resolution sequence stratigraphic framework showed the genetic relationship between the distributions of sedimentary facies and their tectonic settings . the near - source sedimentary systems such as subaqueous alluvial fan and lake - floor fan are often deposed in rise - hemicycles in the steep slope background in the north , the coarse lithology of fan - delta prograded from north to south in fall - hemicycles , and the braided stream facies are formed in the rise - hemicycles in gentle slope background in the south , braided stream facies prograded from sorth to north in the fall - hemicycles , but the lacustrine facies and salt lake facies developed in the middle part of the area
详细的沉积相研究发现,红狮地区第三系发育有冲积扇、水下冲积扇、河流、三角洲、扇三角洲、湖泊和湖底扇7种主要沉积相类型,并对作为区内主要勘探目的层系的下干柴沟组和上干柴沟组进行了以超层序为单位的沉积相平面编图,以较高的时间分辨率揭示了区内沉积相带的平面展布及其在不同构造背景中的分布规律,比如在北部的凹陷陡坡背景下,上升半旋回低水位期通常发育有水下扇、湖底扇等陡岸近源特征的沉积体系,下降半旋回高水位期,扇三角洲相粗碎屑岩由北向南进积;在南部的凹陷缓坡背景下,上升半旋回主要发育辫状河流相,下降半旋回辫状河三角洲相由南向北进积;而中部红柳泉一狮子沟一带则为湖泊相沉积和盐类沉积。 - The sediment stratum in chagan depression is devised into tree supersedences . among them , lower cretaceous can be devised into eight sequences and twenty - two system tracts which have been studied in characteristics of sedimentary cycle , distribution and genetic analysis . after this study , formed mechanism , distribution model and evolvement of sequence have been put forward
查干凹陷共划分出3个超层序,研究目的层下白垩统划分出8个层序, 22个体系域,并进行了层序地层格架的层序沉积旋回特征、层序展布特点和层序成因分析,提出了断陷盆地层序的形成机制、层序地层分布模式与演化模式。
