Aluminum-rich chondrules are less refractory and have lower ^(26)Al abundance compared to Ca-Al-rich inclusions (CAIs) [1-3]. The presence of hibonite grains in a Sharps Al-rich chondrule [2], and of a spinel-fassaite fragment in an Allende ferromagnesian chondrule [4] suggest CAIs as plausible precursors of Al-rich chondrules. To investigate this possibility we have determined major ,-minor-, and rare-earth-element (REE) concentration in dominant mineral phases in CAIs and Al-rich chondrules from Axtell. Aluminum-rich chondrules from Axtell have (^(26)Al/^(27)Al)_i ≤ 3 x 10^(-6) [1]. Bulk compositions for the chondrules were calculated from modal mineral abundances.
