摘要
青藏高原的强烈隆起始于第四纪初期,目前仍处于强烈隆起阶段。根据 钻孔和浅地层剖面仅测量等大量资料的研究,更新世以来东海陆架的周边也处于 快速隆起时期,冰期海退时期的地壳回弹作用有可能加大了东海陆架区的地壳上 升量。 晚更新世末期,东海陆架处于沙漠化环境中,大面积分布的第三纪砂岩是冰 期时期陆架区最重要的物质来源地。冰期海退时期长江和黄河都不能到达陆架区。
The stronger uplift of the Tibetan Plateau began in early Quaternary and it's going on now. Based on the study of many cores data and shallow layer profiler records, all around the East China Sea shelf were also in rapid rising period since Pleistocene. During low-sealevel stage in glacial periods, the rebound maybe increase the ascendind measurement in the East China Sea. During the upper stage of Late Pleistocene, the desertization occurred in the East China Sea shelf. The large range of Tertiary sandstone was the most important material source. The Changjiang River and Yellow River didn't reach the shelf region during low -sealevel stage in glacial periods.
