青藏高原第四纪冰川发育期次及时代确认吸引着众多地质学家的关注 ,尽管它是一个众所周知且极为重要的地球科学问题 ,但古冰川发育时代的确定一直悬而未决。近年来发展成熟的就地成因宇宙核素 (1 0 Be,2 6Al和 2 1 Ne)的表面暴露年龄测定方法为解决该难题带来了曙光。我们应用
Quaternary glaciations in the Qinghai-Tibet Plateau have been identified by many geologists for their period and time. Although it is a well-known and extremely important geoscience issue, the determination of the age of ancient glaciers has been pending. The method of determining the age of surface exposure of well-developed in-situ cosmic nuclides (10 Be, 2 6Al and 2 1 Ne) in recent years has brought a new light to this problem. We apply
