Abstract
The in-situ production rate of cosmogenic He-3 was determined in seven different olivine- or pyroxene-bearing rocks between the latitudes 39 -degrees-N and 46-degrees-N. The integrated production rate over the l ast 17,500 years is about 115 +/- 4 atoms/gram/yr for high latitude at sea level. The variation in the integrated production rate between 20 00 and 18,000 years is less than 30% and is probably on the order of 2 0% or less.
