Abstract
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.
