Trans-lithospheric post-subduction chalcophile element profiles. Primitive mantle-normalised chalcophile element profiles as explained in (a) for: b-d mantle rocks from the Ivrea Zone (b), xenoliths from the Bultfontein kimberlite (c) and Lihir (d); e lower crustal intrusions; f mid-crust intrusions; g upper crustal magmatic–hydrothermal porphyry systems and h epithermal systems. Note: “a” indicates data from this study, whereas other data are cited in reference list. Normalisation values are from Palme and O’Neill60
