Query: Multiple carriers of Q noble gases in primitive meteorites   The main carrier of primordial heavy noble gases in chondrites is thought to
be an organic phase, known as phase Q, whose precise characterization has
resisted decades of investigation. Indirect techniques have revealed that phase
Q might be composed of two subphases, one of them associated with sulfide. Here
we provide experimental evidence that noble gases trapped within meteoritic
sulfides present chemically- and thermally-driven behavior patterns that are
similar to Q-gases. We therefore suggest that phase Q is likely composed of two
subcomponents: carbonaceous phases and sulfides. In situ decay of iodine at
concentrations levels consistent with those reported for meteoritic sulfides
can reproduce the 129Xe excess observed for Q-gases relative to fractionated
Solar Wind. We suggest that the Q-bearing sulfides formed at high temperature
and could have recorded the conditions that prevailed in the chondrule-forming
region(s).
