We have completed metal separation for about 190 meteorites and dissolved 160
metal samples for 36Cl (half-life = 0.3 Myr) measurements. All Cl fractions
were isolated from other elements and purified for analysis by accelerator mass
spectrometry (AMS) at Purdue University. We saved silicate fractions for
further studies including noble gas analysis or 14C measurements. ... The 36Cl AMS
measurements for ~120 Antarctic meteorite samples were performed at Purdue
University. We reported the preliminary results to the MWG and published the
data in the Antarctic Meteorite Newsletter (vol. 29, 2006). This newsletter
serves as a mean to quickly communicate potentially interesting results prior
to final publication.
