南极洲高海拔岩石表面有地球上最古老的宇宙成因核素暴露年龄,可以追溯到中新世。汇编所有可用的3 He,10 Be,和21 Ne的同位素年龄数据从南极大陆表明,暴露的历史记录这些表面延伸回,但不是之前,中新世中期冷却在14-15 Ma。在高海拔地区,这种冷却意味着一种气候的转变,在这种气候中,存在液态水和生物群,可能有助于表面风化和侵蚀,而在极地沙漠气候中,几乎所有的风化和侵蚀过程都被关闭了。从中新世中期到现在,这种气候似乎一直没有间断。
High-elevation rock surfaces in Antarctica have some of the oldest cosmogenic-nuclide exposure ages on Earth, dating back to the Miocene. A compilation of all available3He,10Be, and21Ne exposure-age data from the Antarctic continent shows that exposure histories recorded by these surfaces extend back to, but not before, the mid-Miocene cooling at 14–15 Ma. At high elevation, this cooling entailed a transition between a climate in which liquid water and biota were present and could contribute to surface weathering and erosion, and a polar desert climate in which virtually all weathering and erosion processes had been shut off. This climate appears to have continued uninterrupted between the mid-Miocene and the present.
