The isotopic composition of ytterbium in meteoritic and terrestrial materials was measured using a solid-source mass spectrometer. Isotopic abundances of meteoritic and terrestrial Yb agree within experimental errors. The relative isotope abundances for reagent Yb are 0.00429, 0.0964, 0.4512, 0.6887, 0.5075, and 0.3997 for Yb-168, Yb-170, Yb-171, Yb-172, Yb-173, and Yb-176 relative to Yb-174, respectively. Apart from linear mass fractionation, these data are in agreement with other published data. The concentration of Yb in 21 stony meteorites was determined using the isotope-dilution method. In general, the agreement between this work and other published data is excellent.
