What is this layer?
Locations and geochemistry for samples with sulfur (S_pct) values (≥1%) for mafic–ultramafic intrusive rocks. Geochemical data are derived from the Geological Survey of Western Australia geochemistry database (WACHEM) via the Geochemistry — RECALC and Geochemistry — mafic–ultramafic intrusion layers. These samples are more likely to represent rocks that have undergone sulfur addition and saturation.
