aluminum inclusions), ~15 microns and smaller, have been identified among comet 81P/Wild 2 dust returned by Stardust. We have proposed to measure 26Mg ex-cesses in these objects, resulting from decay of initial radiogenic 26Al, in order to compare their crystalliza-tion ages to those of meteoritic CAIs, many with Ôca-

Read Onural History. To achieve the necessary micron to sub-micron particle size, we ground ~ 75 mg of each sam-ple in an isopropanol slurry using a McCrone micro-nizing mill. Because sulfides of this grain size are es-pecially prone to oxidation due to the large surface area of the grains, we performed all sample preparation in N2-purged glovebags ...
