拐点年龄

径迹年龄分布、AFT曲线拐点年龄和区域抬升剥蚀时间的对比分析结果表明，合肥盆地在早白垩世构造热事件之后的104Ma以来总体处于抬升冷却过程，后期快速抬升冷却事件主要发生在±55Ma。

The fission track ages and the AFT curve break age , as well as the regional uplift-erosive time , reveal that the uplift-cooling process following the tectonic-thermal event has developed since 104 Ma and a later rapid uplift-cooling event occurred mainly around ± 55Ma .
