| 1. | Another aspect to consider is the fate of an abandoned delta lobe after the sediment supply had moved elsewhere .
要考虑的另一方面是沉积物源被移到别处之后被抛弃的三角洲朵体的命运。 |
| 2. | The tectonic movement controls different types of sequences by controlling subsidence of basement and sediment supply rate
构造运动通过控制基底的沉降幅度和物源供给速度控制层序类型。 |
| 3. | The formation and evolution of the sequence stratigraphy of the yanchang formation are governed by slow tectonic subsidence , warm humid climates , sediment supply and lake - level fluctuations
延长组层序地层的形成与演化主要受控于当时缓慢的构造沉降、温湿气候、陆源碎屑物源供给及湖平面升降等地质因素。 |
| 4. | The sediments in the core are weakly weathered , lightly abraded and bad sorted , they have the same feature as river sediment , which is derived from near source and did not experience seriously transformation by ocean . due to the rate of insufficient sediment supply the sedimentation rate is low
碎屑矿物风化程度低，磨蚀不显著，分选较差，河流砂特征明显，沉积物来自于近源，由河流输送入海，海洋改造不十分强烈，由于物源供应不足，沉积速率较低。 |
| 5. | 1 based on the analysis of sedimentary structure and sedimentary energy , the facies model was founded . pucheng oil field is tightly adjacent to the boundary fault of dongpu depress , and it is easy to develop fan - delta and sub - fan on this location . in fact it is easy to find the sediment supply of the studying area is mainly from eastern high through the thickness map and its sand - content map
在研究层段共划分长期旋回1个、中期旋回6个和短期旋回27个(短期旋回规模太小，仅能在岩心上识别) ，通过测井曲线的基准面识别和对比，确定了地层的分布，结合基准面旋回内可容空间的变化，对其沉积演化进行了分析。 |
| 6. | Because during the sedimentation of the flood plain - estuary fades , the conditions of sea level rising , tidal regime , sediment supply and accommodation space were suitable for the development of a tidal ridge system , the sand lenses associated with this facies may represent tidal ridge formation in the incised valley
在河漫滩河口湾相沉积期问，由于海平面上升、潮流体系、沉积物供给和可容空间条件适合一个潮流沙脊体系的发育，其中的砂质透镜体可能代表了下切河谷内发育的潮流沙脊。 |
| 7. | The low and flat coastal plain , the vulnerable muddy coast and the radiate sand ridges without external sediment supply in jiangsu province are extraordinarily sensitive to coastal dynamical changes . faced with the possible sea - level rise in the future , inevitably , the region will be exposed to serious impacts comparatively
江苏中部低平的滨海平原、脆弱的淤泥质海岸和缺少外来泥沙供给的辐射沙洲对海岸动力变化异常敏感，面对未来可能的海面上升，该区域必将受到较为严重的影响。 |
| 8. | Depositional cycles on basin scale have been interpreted as the result of depositional response to tectonism such as episodic rifting , polyphasic compressive flexural subsidence and reversion , and differential subsidence of fault blocks ; while the formation of high frequency sequences was attributed to variation in lake level and sediment supply
盆地规模的沉积旋回多是盆地幕式裂陷、多幕挤压挠曲沉降、多期构造反转、断块差异沉降等构造作用的沉积回应；高频层序单元的发育则主要与湖平面和沉积物供给量的变化有关。 |
