摘要: 介绍了利用裂变径迹年龄剖面求取地质构造抬升时间、抬升幅度、抬升速率的方法,列举了江苏滨海凸起、江西弋阳盆地2个应用实例.前者的构造抬升时间为38~15Ma,与本区三垛事件、盐城事件相吻合,抬升幅度大于3100m,抬升速率为20~50m/Ma;后者的构造抬升时间为20~14Ma,抬升幅度为2600m.该研究结果得到了地震资料、地球化学资料的验证.

Abstract: A method for determining time,lift altitude and rising velocity of tectonic uplift by using the fission track dating profile has being introduced.This method has been used for researching the tectonic uplifts of the Binhai Arch located in margin of Jiangsu Province and Yiyang Basin of Jiangxi Province.For Binhai Arch,the uplift time ranges from 38 to 15 million years corresponding to Sanduo event and Yancheng event,and the rise altitude is over 3100 meters,and the rising velocity is from 20 to 50 meters per million years.For the Yiyang Basin,the uplift time is from 20 to 14 million years,and the rise altitude is 2600 meters. Above conclusion has been proved by seismic and geochemical information.

Key words: fission track, fission track dating, tectonic uplift, burial history, original basin, Subei Basin, Yiyang Basin
