Abstract
Measurement of Be-10 and Al-26 concentrations produced by cosmic ray bombar dment within the quartz mineral fraction of surficial deposits and exposed bedrocks (in situ-production) is rapidly becoming an important quantitative tool in geomorphology. Whereas conventional methods provide age control on stratigraphic profiles, surface exposure dating using in situ-produced Be- 10 and Al-26 is particularly well-suited not only for continuous dating but also for quantifying spatial variations and rates of geomorphic processes.
