This paper reports that large isotopic differences in the stable chlorine isotope ratios of meteoritic, mantle and crustal materials do not exist, that carbonaceous chondrites, mantle and crust all have the same 37Cl/35Cl ratios, establishing that there were no nebular reservoirs with distinct isotopic compositions, no isotopic fractionation during differentiation of the Earth and no late Cl-bearing volatile additions to the crust.
