N2 - Although this Book is mainly about potassic igneous rocks and hydrothermal gold and gold–copper mineralization in volcanic arc environments, there is increasing evidence for the genetic association between volatile-rich potassic igneous rocks and iron-oxide-Cu–Au (IOCG) deposits and intrusion-related gold deposits (IRGD) in plume-related within-plate settings. Recent studies discussed in this Chapter suggest that both IOCG and IRGD systems formed above metasomatized lithosphere from hydrothermal fluids connected to mixed basic to felsic alkaline intrusions that were generated in sub-MOHO magma chambers. Importantly, new data also documents the spatial association between Carlin-type gold deposits and high-K magmatism. Examples of IOCG deposits (Olympic Dam, South Australia), IRGD (Fort Knox, Alaska, USA), and Carlin-type gold deposits (Beast, Nevada) associated with potassic igneous rocks are discussed as case studies in more detail.
