Description

We report the presence of cosmogenic 10Be and 26Al in olivines from the Maui Haleakala basalts in which cosmogenic 3He and 21Ne were discovered. Based on production-rate calibrations in quartz crystals from late Pleistocene granite exposures in the Sierra Nevada, the Haleakala crater erosion rates derived from 10Be and 26Al concentrations agree within 10% and give a mean rate of 12 m/Myr, about 40% greater than the rate of 8.5 m/Myr previously derived from 3He measurements. These results establish the feasibility of the simultaneous use for radioactive and stable cosmogenic nuclides for studies of exposure-ages and erosion-rates in basaltic and andesitic terrains.
