Correlated study of initial Sr-87/Sr-86 and Al-Mg isotopic systematics and petrologic properties in a suite of refractory inclusions from the Allende meteoriteThe abundance and the distribution of Al-26, and the initial Sr-87/Sr-86 ratios were determined in a suite of six coarse-grained Ca-Al-rich inclusions from the Allende meteorite, using, respectively, petrographic and chemical characterizations and ion-probe mass spectrometric analyses of the Al-Mg isotopic system, and thermal emission spectrometric analyses of the Rb-Sr system. Results establish a firm association between primitive Al-26/Al-27 and primitive Sr-87/Sr-86 found in each of these inclusions. None of the results required interpretation in terms of heterogeneously distributed Al-26.
