风化和侵蚀过程是研究气候变化和地貌演化的重要课题.剥蚀包括风化和侵蚀.宇宙成因核素可以直接定量研究105 a范围内地表的平均剥蚀速率.自20世纪80年代以来,加速器质谱分析技术的发展推动了宇宙成因核素在地表过程研究中的应用.国内相关的研究多集中在河流沉积物、阶地演化、冰川历史、埋藏年龄等,在地表剥蚀速率研究方面的应用鲜有报道.
Weathering and erosion processes are important topics in the study of climate change and landscape evolution. Denudations include weathering and erosion. Cosmogenic nuclides directly quantify the average surface erosion rate over the 105-year period. Since the 1980s, accelerator mass spectrometry Has promoted the application of cosmic nuclides in the study of the surface processes.Related studies in China mainly focus on river sediments, terra cotta evolution, glacier history and burial age, and few reports have been reported on the application of surface ablation rates.
