Extremely Na and Cl Rich Chondrule Al3509 from the Allende Meteorite

This Ca-Al-rich chondrule is not a replacement product. It has ~10% Na and ~1% Cl. Large excesses of 36S were found uncorrelated with Cl and 26Al/27Al < 3 x 10^-6. It represents the fluid responsible for late alteration in volatile-rich outer layers prior to formation of Allende.
