| 1. | The complex of sand bodies developed in a cyclical sequence of off-lappings edimentary beds . 砂岩复合体发育于退覆沉积层的旋回层内。 |
| 2. | These cyclic sequences are overlain by the lagoon dolomitic mudstones and shales 米级旋回层序之顶覆以厚度不等的 |
| 3. | These cyclic sequences may be divided into three types : " deepening " - upward asymmetrical type , " shallowing " - upward asymmetrical type and symmetrical type 运用旋回等时对比法则对短期基准面旋回层序进行等时对比,并建立等时地层格架。 |
| 4. | Sequence analysis and isochronous correlation of the short - term base - level cycles in the third oil reservoirs of the yanchang formation in the huachi oil field , ordos basin 鄂尔多斯盆地华池油田延长组3油组短期基准面旋回层序分析与等时对比 |
| 5. | In this paper , various types of structure and the relationship between sedimentary dynamic process and strata response of the short cycle sequences is discussed 讨论了短期基准面旋回层序的各种结构类型和沉积动力学过程与地层响应的关系。 |
| 6. | These biostromes and bioherms , together with tidal - flat dolomicrite and muddy dolostone , form circum - tidal flat meter - scale carbonate cyclic sequences with symmetrical facies sequences and fabrics 它们与潮坪相泥晶白云岩和泥质白云岩构成具对称相序组构的环潮坪型碳酸盐米级旋回层序。 |
| 7. | Viewed from the ordered stacking patterns of the meter - scale cyclic sequences in the long - period sequences , twenty - six third - order sequences may be identified in the wumishan formation 因此,七级韵律层、米级旋回层和五级准层序组分别与岁差旋回、短偏心率旋回、长偏心率旋回间存在有成因联系。 |
| 8. | Applying small scale strata units tracking and correlation method , the middle to small strata units of the jurassic middle cycles in the studied area has been tracked and correlated in this paper 本文采用小尺度地层单元的等时追踪对比方法,对研究区侏罗系中相当于中期旋回层序中的中、小层尺度地层单元进行了等时追踪对比。 |
| 9. | Therefore , the seventh - order rhythmites , meter - scale cyclic sequences and fifth - order parasequence sets are correlative in origin with precession of equinox cycles , short eccentricity cycles and long eccentricity cycles , respectively 常常3 - 5个米级旋回层序呈有序叠加构成五级准层序组,少数米级旋回层序还可识别出5个七级韵律层而呈现出1 5的叠加关系。 |
| 10. | 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。 |
