We have analysed the element composition and the context of particles 
collected within the coma of 67P/Churyumov–Gerasimenko with Rosetta’s 
COmetary Secondary Ion Mass Analyzer (COSIMA). A comparison has been 
made between on board cometary samples and four meteorite samples 
measured in the laboratory with the COSIMA reference model. Focusing on 
the rock-forming elements, we have found similarities with chondrite 
meteorites for some ion count ratios. The composition of 
67P/Churyumov–Gerasimenko particles measured by COSIMA shows an 
enrichment in volatile elements compared to that of the investigated 
Renazzo (CR2) carbonaceous meteorite sample.
