| 摘 要： | 对于具有较宽陆架的下刚果盆地,当相对海平面下降时期,陆架区沉积中心向外陆架迁移,形成陆架边缘三角洲.其为深水区提供大量陆源碎屑物质,使低位体系域发育碎屑流沉积、浊流水道及前端扇体系；当相对海平面上升时期,沉积中心后退至内/中陆架,使深水区海侵十高位体系域以深海、半深海原地泥质沉积及泥质碎屑流沉积为主.深水层序以凝缩层段...

| Abstract: | The Lower Congo Basin is a basin with a wide continental shelf.In such a basin,when the relative sea-level falls,depocenters on the inner shelf will shift to the outer to form shelf-margin deltas.It will result in the acceleration of sediment supply to the deep-water area,and then lowstand systems tract,such as debris-flow deposits,turbidites and frontal fan deposits will develop.By contrast,when the relative sea-level rises,depocenters will shift towards the middle and inner shelf,then transgressive system... |
