Abstract

The cycle of sulfur In the earth's crust is a critical aspect of understanding the sources, pathways and processes governing the formation of many mineral systems. In my study, the cryptic source and transport processes of sulfur, a key ligand in the transport and deposition of gold and thus an exploration vector for it, are investigated. My results show that Archaean sulfur with a +MIF-S anomaly (d³³S, d³⁶S) from carbonaceous rocks Is a major contributor of sulfur to gold mineralising systems in both the Archaean and the Paleoproterozoic supporting the sedimentary derivation of gold in many gold deposits.
