Аннотация

Large Igneous Provinces (LIPs) are huge-volume short-duration mostly mafic (-ultramafic) intraplate magmatic events that occur every 20-30 Myr since at least the Neoarchean. They consist of flood basalts, dyke swarms, sill complexes, mafic-ultramafic layered intrusions, and are also associated with felsic magmatism, carbonatites and cases kimberlites. LIPs contribute to the formation of major ore deposits, and also to hydrocarbon deposits and aquifers. I review the links between LIPs and major ore deposits globally, and also within Russia. I also present lessons from LIPs on Venus to understand magmatic sulphide deposits on Earth.
