| 2. | Grain - size characteristics of xinkaipu section and its relationship with the paleoflood 长沙新开铺剖面纹层沉积序列及其反映的古洪水事件 |
| 3. | 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。 |
| 4. | The feature of the sedimentary succession of the epicontinental sea basin in the study area was analyzed by means of the stochastic math model , markov chain 摘要运用马尔柯夫链随机性数学模型对研究区陆表海盆地沉积序列特性进行了分析研究。 |
| 5. | Cyclicity character is one of the most important attributes of depositional strata , and it looks more important in the terrestrial sediments 摘要旋回性特征是沉积岩层最为重要的属性之一,尤其在对于区域地质背景波动做出敏感响应的陆相盆地沉积序列当中更是如此。 |
| 6. | Sequence with features of proximal storm deposits associates closely with sequence with features of distal storm deposits at the longtangwan section , possibly resulting from differences in strength of storm fluids or in landing path of storm fluid 另外,不同的、类似于近源和远源的风暴沉积序列出露于同一剖面的相邻层位,可能反映了风暴登陆路径或者风暴流强度的差别。 |
| 7. | In the end , i discussed the formation and evolution character of long sequence cycles , which had close relation to asynchronous thrust action of longmen mountains and micang - daba mountains 详细讨论了短期、中期和长期旋回层序的结构类型、沉积序列、叠加样式和分布模式,最后探讨了长期旋回层序的形成、演化特征以及与龙门山和米仓山?大巴山两构造带非同步逆冲推覆作用的关系。 |
| 8. | Because of their prominent advantages compared with other achieves of environmental change , the study of high - resolution sequence of environmental change during the late quaternary mainly depends on the polar ice - core and deep ocean sediment 由于冰芯与深海沉积和其它环境演化信息的记录载体相比优势明显,国际上的晚第四纪高分辨率环境演化序列研究多采用冰芯与深海沉积序列。 |
| 9. | On the basis of detailed facies division and depositional array , taking the theory of high - resolution sequence stratigraphy as a direction , the text divides 1 - 3 sand beds into one middle - term , five short - term and fourteen - sixteen supershort - term base level cycle sequences 在精细的沉积相划分和沉积序列分析的基础上,以高分辨率层序地层学理论为指导,对胜一区沙二段1 - 3砂组进行高分辨率层序地层分析。 |
| 10. | According to the abundance well logging , mud logging and core analysis data , gaotaizi reservoir has been classified into four sand group with the principle of cycle comparison and classified control . based on the detailed study of lithologic character , sedimentary structure , paleontologic fossils , depositional sequence , rock association and logging data , the microfacies of the studied area are divided into such seven types : subaqueous distributary channel microfacies ; river mouth bar microfacies ; subaqueous interdistributary channel microfacies ; subaqueous crevasse channel microfacies ; subaqueous natural barrier microfacies ; distal bar microfacies ; delta front sheet sand microfacies . the characteristic of each sedimentary microfacies are described detailedly 通过研究大量测井、录井资料和岩芯资料,依据“旋回对比,分级控制”的原则,把研究区高台子油层划分为g 、 g 、 g 、 g四个砂层组。通过对研究区岩性、沉积构造、古生物、沉积序列、岩石组合及测井曲线特征进行研究的基础上,认为研究区高台子油层属于三角洲前缘亚相沉积,并将研究区沉积微相划分为:水下分流河道、河口坝、水下分流河道间、水下决口扇、水下天然堤、远砂坝、席状砂等七种微相类型。 |
