There were seven sessions related to igneous petrology in the 31 st International Geological Congress, namely, granitic magmatism and mineralization, granite system and the process of the Proterozoic lithosphere, basalts, genesis and emplacement of alkaline intrusions, carbonatites, kimberlites, lamproites and related rocks, organic acidic and intermediate volcanic rocks, and volcanic processes. Recent progress and the trend of development in igneous petrology have been discussed in this paper based mainly on the 31 st IGC as well as other data. It is concluded that igneous petrology has made great progress in such fields as earth's materials science, lithoprobe, large igneous provinces and mantle superplume, mantle dynamics, physics in magmatic processes, and ultrahigh_pressure experiments.
