It has been assumed that CI chondrite meteorites are
the least affected by fractionation processes, given their
higher volatile/refractory ratio than other meteorite classes
(Lodders et al. 2009). However, it had not been demon-
strated that the CI chondrites are completely lacking in
fractionation effects for elements more refractory than H,
C, N and O relative to the primordial state. If our nding is
conrrmed, then a mechanism for this fractionation will need
to be sought.
