Scientific paper
The nickel isotopic composition of meteoritic materials is analyzed by high-precision mass spectrometry. The samples treated include almost all the meteorite types for which large isotopic anomalies have been reported for oxygen, silver, magnesium, and titanium. The samples are Cl, C3, L, LL, H and E chondrites, IVB irons, Eagle Station pallasite, and inclusion, matrix and 'whole rock' samples of the Allende meteorite. No anomaly is found for nickel isotopic compositions within an accuracy of 0.7 part per thousand for Ni-61/Ni-60, 0.4-0.08 part per thousand for Ni-62/Ni-60, and 1-1.5 parts per thousand for Ni-64/Ni-60.
