The particles reanalysed in this study were obtained from the
NASA Johnson Space Center (JSC) Cosmic Dust Collection. The
reanalysis of the particle L2008 P9 indicates typical assemblage
of olivine - pyroxene. This sample can be classified as a
chondritic porous IDP with the metallic phase grain containing
essential amount of nickel and copper (the latter element is most
probably due to instrumental artefact). The chemical composition of
the particle L2011 S5 corresponds mostly to an assemblage of
pyroxene phase - (Mg,Fe,Ni)SiO_3 roughly 75 wt.% and a sulphide
phase - probably pyrrhotite (Fe,Ni)S about 25 wt.%.
