第四纪东海的海进层序和海退层序
|
摘要
通过对东海陆架4000km电火花单道地震资料的判读,并与位于东海外陆架的钻孔DZQ4对比,分析地震地层的特点、沉积相和沉积环境,推测形成年代,探讨第四纪东海海进层序与海退层序,以及与海面变化的响应.研究表明第四纪东海海面随着全球气候冷暖波动而升降,海面上升时,太平洋潮波对东海陆架的作用加强,北西至南东向往复潮流塑造了潮流沙脊,地震剖面显示海进层序;海面下降时,长江三角洲向海进积,地震剖面显示水下三角洲的海退层序.随着第四纪海面多次升降,东海外陆架地层的海进层序与海退层序周期性交替分布,它们与海面变化曲线存在很好的对应关系.由于东海陆架坡缓,海面数十米升降可以造成岸线在数百公里范围内进退,又由于长江的大量输沙,水下三角洲和潮流沙脊的规模都很大.自氧同位素8期以来,共发育了3期较大潮流沙脊和4期大规模的水下三角洲。
