The objective of this work is to present a first assessment on the age of the glacial features of the Serra da Estrela, in the central Portugal, Iberian Peninsula (40°19′ N, 7°37′ W, 1993 m), using Cosmic-Ray Exposure dating (in situ cosmogenic ³⁶Cl). A total of 6 samples were dated, 4 extracted from exposed moraine boulders and 2 from glacially polished bedrock surfaces. Despite the low number of samples, the results are consistent, reinforcing previous dating obtained by other methods and geomorphological and paleoclimatic information. The maximum extension of the glaciers occurred at the end of the Penultimate Glacial Cycle (Marine Isotope Stage 6), during Heinrich Stadial 11, around 140 ka. At the end of the Last Glacial Cycle, slightly before the Last Glacial Maximum, at around 30 ka, the Estrela glaciers reached again a similar extent. Finally, the glaciers disappeared from the Serra da Estrela at the beginning of the Bølling-Allerød Interstadial, at around 14.2 ka. These data confirm a certain synchronicity in the major glacial phases in most the Mediterranean and also European mountains, although there are notable differences in the maximum extent in the two cycles.

这项工作的目的是利用Cosmic对葡萄牙中部伊比利亚半岛埃斯特雷拉山脉（Eerra de Estrela）冰川特征的年龄进行初步评估（40°19′N，7°37′W，1993 m）。 -射线曝光测年（原位宇宙成因³⁶Cl）。总共标出了6个样本，其中4个是从裸露的冰ora中提取的，另外2个是从冰川抛光的基岩表面提取的。尽管样本数量很少，但结果是一致的，这加强了通过其他方法以及地貌和古气候信息获得的先前年代。冰川的最大扩展发生在倒数第二次冰河循环的末期（海洋同位素第6阶段），即海因里希（Heinrich）Stadial 11时期，约140 ka。在最后一次冰川循环的末期，大约在最后一次冰川最大值之前，大约30 ka，埃斯特雷拉冰川再次达到了类似的程度。最终，在Bølling-AllerødInterstadial始于14.2 ka时，冰川从埃斯特雷拉山脉（Serra da Estrela）消失了。
