Late-formed halogen-rich phases in a refractory inclusion and a chondrule from the Allende meteorite exhibit large S excesses that linearly correlate with the chlorine concentration, providing strong evidence in support of the existence of the short-lived nuclide Cl (mean life of 0.43Myr) in the early solar system. The inferred Cl /Cl ratios at the time when these phases formed are very high ( 4 ; 10 ) and essentially the same for the inclusion and the chondrule and confirm the earlier report… CONTINUE READING
