首次对格罗夫山地区漂砾的暴露年龄进行的研究表明,萨哈罗夫岭冰原岛峰的两块漂砾样品的~(10)Be最小暴露年龄分别为1.24±0.11Ma和1.37±0.12Ma,~(26)Al最小暴露年龄分别为0.90±0.12Ma和0.44±0.04Ma。萨哈罗夫岭附近冰面上的漂砾样品的~(10)Be和~(26)Al最小暴露年龄分别是0.47±0.3Ma和0.44±0.04Ma。考虑到误差,萨哈罗夫岭三块漂砾的最小暴露年龄与相近高程的基岩样品的最小暴露年龄基本一致。因此,在利用原地生成宇宙成因核素测年技术对东南极内陆格罗夫山地区的冰川消涨历史进行研究时,基岩和漂砾暴露年龄所反映出的冰川演化历史是明显吻合的。
The first study of exposure age of boulders in the Grove Mountains showed that the minimum exposure age of ~ (10) Be for the two boulders in the Sakharov Ridge is 1.24 ± 0.11 Ma and 1.37 ± 0.12, respectively Ma, ~ (26) Al minimum exposure ages were 0.90 ± 0.12Ma and 0.44 ± 0.04Ma respectively. The minimum exposure ages of ~ (10) Be and ~ (26) Al of boulder samples on the ice surface near Sakharov Ridge are 0.47 ± 0.3Ma and 0.44 ± 0.04Ma, respectively. Taking into account the error, the minimum exposure age of the three boulders in the Sakharov Ridge is basically the same as the minimum exposure age of bedrock samples of similar elevation. Therefore, when studying the history of glaciers disappearing in the Grove Mountains in the southeastern part of Antarctica, using in situ generation of cosmic dating techniques, the history of evolution of glaciers reflected by the exposed ages of bedrocks and boulders is obviously consistent of.
