Garrett lavas show ultra depletion in incompatible element, consistent with re-melting.

Constant δ³⁴S${\delta }^{34}\mathrm{S}$ values, indicating that S isotopes are insensitive to partial melting processes.

This allows estimating a sulfide-silicate melt S isotopic fractionation to be 0.0±0.3‰$0.0\pm 0.3\mathrm{‰}$.

An upper limit for the S amount in the hadean matte is $3.36\times {10}^{24}\text{g}\mathrm{S}$ (i.e. ∼10% of the bulk terrestrial S).
