晚更新世以来山东半岛北部沿海地区的构造抬升速率

UPLIFT RATES ALONG NORTHERN SHANDONG PENINSULA SINCE LATE QUATERNARY

根据构造地貌与新构造特征，推算了晚更新世以来山东半岛北部沿海地区的构造抬升速率。结果表明，晚更新世以来不同地段平均构造抬升速率不同，金牛山断裂以东地区为０．１５ｍｍ／ａ，断裂以西地区为０．５０ｍｍ／ａ；龙口盆地２．４万年前后曾发生过幅度７～９ｍ的断陷。此外，同一地段不同时段的抬升速率也有差异，但非常接近平均速率。

Based on the tectonic landforms and neotectonic characteristics,the uplift rates along northern Shandong Peninsula since Late Quaternary was calculated.The results show that the average uplift rates in different parts are different.The rate east of Jinniushan Fault Zone is 0 5mm/a,while the one west of it is only 0 15mm/a,but Longkou Fault Basin subsided 7 8m at about 24kaB.P.The rates of different times in the same part are also different,but they are very close to the average rates since Late Quaternary.
