SS-8: Testing links among large igneous provinces, iron formations, and volcanogenic massive sulfide deposits

Convenors: Andrey Bekker (, Richard Ernst (, Wouter Bleeker (

Emplacement of Large Igneous Provinces (LIPs) has been linked to mantle plume events. It has been also argued that submarine hydrothermal activity associated with mantle plume events contributed to enhanced delivery of base metals, iron and manganese to the oceans, favouring formation and preservation of VMS deposits in back-arc settings and iron and manganese deposits on continental shelves. Growing age resolution for LIPs, IFs, and VMS deposits allows now to test temporal association among mafic to ultramafic magmatic activity and these deposits, as well as explore potential cause-and-effect relationships. Submissions providing temporal resolution on LIPs, IFs, and VMS deposits, dealing with specific deposits and mantle plume events, and exploring cause-and-effect relationships are encouraged.          

SS-9: Layered intrusions: new paradigms and approaches to understanding magmatic processes

Convenors: James Scoates (, Jim Miller (

Layered intrusions have long captivated geologists with their remarkable textures and structures that record the diversity of processes of magma differentiation, recharge, and venting. They are also host to a range of magmatic and hydrothermal mineral deposits whose formation is intrinsically tied to the emplacement and crystallization histories of these bodies and their interaction with country rock. Recent progress in concepts concerning the evolution of layered intrusions is based on integrated studies involving field observations, textural interpretations, experiments, fluid dynamic modeling, and geochemistry and geochronology. Contributions on all subjects relevant to advancing our understanding of processes involved in the development of layered intrusions are strongly encouraged.    

Also includes the following fieldtrip:
