| 摘 要： | 通过对黄河三角洲几个钻孔的分析.将其自上而下划分成3个海相层和3个陆相层,并且划分为1个4级层序(准层序)和4个5级层序。每个层序代表了一次海平面的升降旋回。4级层序的海退沉积与末次冰期的后期对应,海平面下降最大时期是末次冰期最盛期(LGM)的反映。 |
| 关 键 词： | 末次盛冰期 浅地层 海平面 层序 |

| Abstract: | According to stratigraphic analysis of several holes,the formations of the Yellow River delta can be divided into three marine and three continental beds from top to bottom.And the environmental evolution can be explained by these facies.The stratigraphic sequences,including one parasequence and four fifth-level sequences,have been identified.Each sequence corresponds to relative sea-level rising and falling cycles.The regressive period of the parasequence was the late stage of the Last Glacial,when two fif... |
