ABSTRACT
Presolar silicates are, apart from nanodiamonds, the most
abundant type of stardust and have been found in several primitive
meteorites. Together with Acfer 094 and ALHA77307, the ungrouped
C3 chondrite Adelaide and the K chondrite Kakangari have been
characterized as primitive with pristine matrix material. We are
investigating the latter two meteorites in order to evaluate their
presolar grain inventories and the degree to which these have been
affected by nebular and/or parent body processing.
