Abstract
Trace quantities of silver in the iron meteorite Canyon Diablo were isolated by chemical procedures with an average yield of 80% The isotopic composition of 5 samples of silver from the meteorite was measured on a 12-inch radius of curvature, double-focusing, fast-sweep mass spectrometer. The isotopic composition of 18 samples of terrestrial silver was measured for comparison. The meteoritic and terrestrial ratios of Ag107/Ag109 were found to be identical to within 1%. The silver content of Canyon Diablo is 58 parts per billion from isotopic dilution analyses of aliquots of the meteorite samples. Blanks were less than 10% of the sample size in our analyses. We are thus unable to confirm a previous report of a 4% excess of Ag107 for Canyon Diablo.
