Data for Quaternary Science Reviews Paper JQSR 5235- Evidence for slow late-glacial ice retreat in the upper Rangitata Valley, South Island, New Zealand.

Data relating to the collection of CRN samples from boulders on moraines on the lower flanks of the Butler and Brabizon Downs in the Rangitata Valley New Zealand. The study aimed to test whether the moraines related to one or many glacial advances and recessions. The study in QSR shows that the moraine sequence on the lower flank of the valley relates to a retreat of a single glacier at the end of the last ice age. It shows gradual ice evacuation from this area between c 21 and c 17 ka.

本数据集包含采自新西兰朗吉塔塔谷巴特勒丘陵与布拉比宗丘陵下部山坡冰碛物砾石的宇宙成因核素（Cosmogenic Radionuclide, CRN）样品采集相关数据。本研究旨在验证这些冰碛物对应单次还是多次冰川进退事件。发表于《第四纪科学评论》（Quaternary Science Reviews, QSR）的该项研究表明，该河谷下部山坡的冰碛序列对应末次冰期末期单条冰川的退缩过程，研究显示约21千至17千年前，该区域的冰川逐步后撤消融。
