High precision Al-Mg isotopic sims microanalysis of Wark-Lovering rims on Ca-Al-rich inclusions

Two tables. One contains magnesium and aluminum isotopic data for Wark-Lovering rim phases on six refractory inclusions from CV3 carbonaceous chondrites. The second table contains corresponding isotopic data from the interior of one of the inclusions, Vigarano USNM 477-5. All data was collected using secondary ion mass spectrometry (SIMS, a.k.a ion microprobe)
