The studied dataset from the Southern Carpathians permitted the quantification of a considerable amount of inherited ¹⁰Be in the glacial boulders and bedrock samples the cirque area. The samples from the glacial phases of largest extension display no signs of significant inheritance, and enabled the establishment of a deglaciation chronology in the southern valleys of the Retezat Mts. The timing of the maximum glacier extent (20.6^+0.8/_−1.3 ka) coincided with the Last Glacial Maximum, which was followed by five deglaciation phases during the Lateglacial having partly overlapping ages due to fast glacier retreat (at 18.4^+0.7/_−1.1 ka; 16.9 ± 0.9 ka, 15.8^+0.9/_−0.6 ka, 15.6 ^+0.8/_−0.8 ka and 14.4 ± 0.5 ka) but could be distinguished by the position of their terminal moraines.

This is the first study providing evidence on the maximum ice extent coinciding with the Last Glacial Maximum and subsequent fast deglaciation during the Lateglacial in several valleys of the Retezat Mts. The currently available geochronological data do not support the assumption of any major glacial re-advance after Greenland Stadial 2.1a in the Retezat Mts.

Given the lack of independent geochronological data, the amount of inherited cosmogenic nuclides is tentatively estimated by accepting the youngest cosmic ray exposure age(s) as the time of moraine deposition and abandonment by the glacier. The calculated amount of inherited ¹⁰Be enables the estimation of a glacial erosion depth of 1.1–1.6 m for the bedrock samples and 1.4–1.8 m for the glacial boulders. The duration of the ice-covered and ice-free periods was adjusted in relation to independent paleoenvironmental and paleoclimatological data. The glacial denudation rate in the cirques was estimated at 19–28 mm/kyr and 24–33 mm/kyr for bedrock and boulders, respectively.

The limited glacial erosion in the cirques during the last glaciation is attributed to frozen-bed conditions with no considerable glacial deepening during the more extended glacial phases. Only when warming led to the retreat of the glaciers to their cirques, they become steeper and shift to being warm-based and thus more erosive. However, the limited time spent under these conditions appears to be too short to remove material from the cirque floors in sufficient depth (>3 m) to reset the cosmogenic clock. This suggests that the development of the cirques must have taken place during several subsequent glacial phases, providing an indirect confirmation of repeated Quaternary glaciations in the Retezat Mts.

来自南喀尔巴阡山脉的研究数据集允许量化冰砾和基岩样品中冰河面积中相当数量的遗传¹⁰ Be。来自最大扩展期的冰川期的样品没有显示出明显的遗传迹象，并且可以在Retezat山的南部山谷中建立冰消年表。最大冰川范围的发生时间（20.6 ^+0.8 / _-1.3 ka）与最后一次冰川期相吻合，随后是晚冰川期的五个冰川消融阶段，由于冰川的快速退缩（年龄段为18.4 ^+0.7 / _{-1.1），它们的}年龄部分重叠。ka; 16.9±0.9 ka，15.8 ^+0.9 / _-0.6ka，15.6 ^+0.8 / _-0.8 ka和14.4±0.5 ka），但可以通过其末端mo的位置加以区分。

这是第一项研究，为Retezat山的几个山谷中的最大冰范围与最后一次冰期最大值以及随后的晚冰期快速脱冰相吻合提供了证据。目前可用的地质年代数据不支持Retezat山的Greenland Stadial 2.1a之后任何重大的冰川再造。

鉴于缺乏独立的年代学数据，通过接受最年轻的宇宙射线暴露年龄作为冰ora沉积和被冰川抛弃的时间，来初步估算继承的宇宙成因核素的数量。通过计算得出的¹⁰ Be的继承量，可以估算出基岩样品的冰川侵蚀深度为1.1-1.6 m，而冰砾的估算值为1.4-1.8 m。相对于独立的古环境和古气候数据，调整了覆冰和无冰期的持续时间。对于基岩和巨石，冰团的冰河剥蚀率估计分别为19-28 mm / kyr和24-33 mm / kyr。

在最后一次冰期期间，回旋中有限的冰河侵蚀归因于冰床条件，在更扩展的冰期中没有明显的冰河加深。只有当变暖导致冰川退缩到它们的cirque时，它们才变得更陡峭并转变为以温暖为基础，因此更具侵蚀性。但是，在这些条件下花费的有限时间似乎太短了，无法从圆盘地板上以足够的深度（> 3 m）清除材料以重置宇宙时钟。这表明圆环的发育必定发生在随后的几个冰川期，间接证实了Retezat山中第四纪冰川的重复。
