英文摘要	对大青山东段4件基岩样品进行磷灰石裂变径迹研究,获得该区晚中生代以来的隆升-剥露历史,并探讨大青山现代地貌的形成。样品的磷灰石裂变径迹年龄为57.7±3.8~50.4±3.3 Ma,封闭径迹长度分布在10.7±0.4~9.9±0.1μm之间。热历史模拟结果表明,大青山地区存在晚白垩世(约100~90 Ma)和中-晚中新世(13.5~7 Ma)以来两个快速抬升冷却阶段,13.5~7 Ma以来是本区剥露最快的时期,这一阶段的隆升造就现今大青山的地貌格局。; Four bedrock samples, collected from the eastern segment of Daqing Mountain, were analyzed using apatite fission-track (AFT) method. This elucidates the uplift-exhumation history of this area since the Late Cretaceous — in particular, when the present geomorphology of Daqing Mountain was shaped. The AFT ages range from 57.7±3.8 Ma to 50.4±3.3 Ma and the track length is between 10.7±0.4μm and 9.9±0.1μm. Modeling of the fission track data suggests two stages of rapid uplift and cooling, 100-90 Ma and since 13.5-7 Ma. The second cooling stage (since 13.5-7 Ma) was characterized by the fast uplift-exhumation in this area, resulting in the present geomorphology of Daqing Mountain.; 国家重点基础研究发展计划; 中国地质调查局项目; 中国科学引文数据库(CSCD); 1; 57-65; 53
