| 1. | Eustatic lake level and source change had resulted in intercalation development in braided delta system 湖面的升降和物源的摆动使辫状三角洲沉积体系中发育夹层。 |
| 2. | Issyk - kul lake level fluctuation during 1860 - 2005 and its relation with regional climatic and hydrological changes 2005年伊塞克湖水位波动与区域气候水文变化的关系 |
| 3. | The rock on the right has a whitish crust of minerals , indicating that it was submerged until the lake level dropped 右边的这块表面结了一层白白的矿物质,显示它在水位下降之前是泡在水里的。 |
| 4. | Compared c13 & o18 isotope analysis curve with lake level curve , further analyzed palaeoenvironment 通过分析、对比碳氧同位素曲线与湖平面升降曲线,对古沉积环境的变化规律有了进一步的认识。 |
| 5. | Sediment cores from lake titicaca itself also chronicle the event , showing a 33 - foot drop in the lake level at the time 提提卡卡湖沉淀物的岩芯也记载了这一事件的年代,表明在当时湖面下降了33英尺。 |
| 6. | Fan - delta sedimentation formed under the environment of lake level frequently varying taking the first member of kongdian formation , huanghua depression as an example 以黄骅坳陷枣园油田孔一段沉积为例 |
| 7. | That the black mudstone deposited in deep water interbedded with salt and gypsum deposited in shallow water shows that during the sedimentation of 3 ( superscript rd ) and 4 ( superscript th ) sub - member , the lake level changes frequently 也正是由于湖平面变化频繁,在沉积中心的周围主要物源方向上形成一系列低水位期的砂体。 |
| 8. | Being primarily controlled by northwest faults , cretaceous of jiyang depression contained several isolated basins , and lake levels of these isolated basins were instable , but on the whole , shore and shallow lake sub - facies is in the majority 北西向断层的活动对沉积起到主要的控制作用,在其控制下,白垩纪济阳坳陷为一相互分割的山间盆地,湖盆范围时大时小,湖水深度不断变化,总体湖水较浅,主要发育滨浅湖亚相。 |
| 9. | 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。 |
| 10. | On the basis of the feature of paleostructure , paleogeography and lake level fluctuation in chang - 6 to chang - 8 oil - bearing layers , this text researchs paleogeographic feature and evolution . chang - 8 stages are the early days of lake basin outspread , chang - 7 stages are steadies stage of lake basin outspread , chang - 6 stages are shrinkage of lake basin , the lake level slowly droping , lake strandline moving eastward 根据古构造、古地理、湖平面升降等特点研究了长_ 6 ?长_ 8期岩相地理特点及其演化,长_ 8期是湖盆扩大的初期;长_ 7期为湖盆扩大阶段中稳定期;长_ 6期为湖盆扩大阶段中开始萎缩,湖平面继续缓慢下降,湖岸线向东迁移。 |
