| 1. | The beginning and the end of each significant depositional pattern is directly related to changes in position of sea level with respect to river deltas .
每一种有意义的沉积形式的开始和结尾，都与对应于河流三角洲的海平面位置的变化有直接的关系。 |
| 2. | River deltas are difficult places for map makers
河流三角洲对于地图编制者是个特殊的地方。 |
| 3. | River - delta marsh
河流三角洲沼泽 |
| 4. | Geographically , jiangmen municipality is located in an alluvial plain in river delta , with low hills dotted crisscrossed rivers and fertile soil
江门市属河流三角洲冲积平原，低山丘陵错落其间，河网纵横，土地肥沃。 |
| 5. | As the oceans swell with water from melting ice sheets , it is the crowded river deltas in southern asia and egypt , along with small island nations , that are most at risk
冰川融化，海平面上升，河流三角洲密布的南亚和埃及以及其他的一些小的岛屿国家将最先遭遇风险。 |
| 6. | By looking into the cores , analyzing of granularity and ichno - fossils , the paper has ascertained the basin as a normal fluvial delta deposital system , which amends the former view that believed the basin should be a fan - delta system
通过本区大量的岩心观察、粒度分析、遗迹化石分析，修改了前人认定的其为扇三角洲沉积体系的观点，将其确定为正常的河流三角洲体系。 |
| 7. | It is suggested in this paper that the sediment of the high stand system tract is mainly composed of fine - grained sediment , hardly of the large scale of fluvial - delta because of the low dip of the ramp , low subsiding rate and low sedimentary rate in basin
研究表明，盆地基底沉降幅度小、坡度极为平缓、沉积速率很低，因此导致层序内的高位体系域多以细碎屑沉积为主，大型河流三角洲沉积基本不发育。 |
| 8. | Member - one of nenjiang group is divided into sa 0 sand - group . the same points of medimentary microfacies types and distribution by developed in many sand groups lies in that they dominate with river delta and shore - shallow lake in west and dominate with deep lake - semi - deep lake and contain gravity flow . the change of sediment scope of each sand - group makes deep lake - semi - deep lake and sublacustrine fan sediment of ga 0 and pu 2 sand - groups not being developed during the lest sediment area , but the deep lake - semi - deep lake and sublacustrine fan sediment during the largest sediment scope of sa 0 is well developed
多数砂组发育的沉积微相类型和分布的共同之处在于，西侧多以河流三角洲和滨浅湖沉积为主，东部以深湖?半深湖为主其中夹有重力流，但由于各砂组沉积范围的变化，造成沉积区最小时期的高0 、葡2砂组深湖?半深湖及湖底扇沉积不发育，而沉积范围最大时期的萨0砂组深湖?半深湖及湖底扇沉积极其发育。 |
| 9. | From csql to csq5 , the barrier system was the main system . from psql to psq5 , the carbonate ramp was the main system and from psq6 to psq8 the main system was fluvial and fluvial - delta system in brackish basin . from psq9 - psql2 , the main system turned to the fluvial - delta system
晚石炭世csq1 ? csq5层序以碎屑海岸障壁?泻湖和碳酸盐缓坡沉积体系为主；早二叠世早期psq1 ? psq5层序以碳酸盐缓坡沉积体系为主，早二叠世晚期psq6 ? psq8层序以半咸水盆地河流、河流三角洲沉积体系为主；中二叠世psq9 ? psq12为陆相冲积扇、河流、湖泊三角洲沉积体系。 |
