Coupled sulfur-silicon isotopes reveal supracrustal origin of Archean continents
O. Global compilation shows that granitoids formed after 3800 Ma uniformly contain enriched δ³⁰Si and non-zero Δ³³S, implying that most, if not all Archean continental crusts were derived from partial melting of supracrustal sources rather than unaltered mafic cumulates.
