The Beypazarı Granitoid is an arc-related intrusion in the Central Pontides, Turkey. This study presents apatite fission track (AFT) ages of the intrusion to shed some light on collision-related cooling/exhumation history of the central Pontides. The AFT ages from different altitudes (506–805-1110 metres above sea level) of the Beypazarı Granitoid yield around 65 ± 3 Ma. This indicates a rapid cooling/exhumation for the intrusion around 65 Ma, which is attributed to the commencement of the collision event in the region. Integration of these ages and low-temperature thermochronology literature suggests a progressive collision propagation towards the margins of the collision system.

BeypazarıGranitoid是土耳其中部庞德特斯群岛上与电弧有关的入侵。这项研究介绍了侵入体的磷灰石裂变径迹（AFT）年龄，以期为中庞德特斯中与碰撞有关的冷却/掘尸历史提供一些信息。BeypazarıGranitoid的不同海拔（海拔506-805-1110米）的AFT年龄约为65±3 Ma。这表明入侵在65 Ma左右迅速冷却/掘出，这归因于该地区碰撞事件的开始。这些年龄和低温热年代学文献的综合表明，碰撞逐渐向碰撞系统边缘传播。
