从31届地质大会看火成岩石学的研究动向

Development Trend of Igneous Petrology Based on the 31^(st) International Geological Congress

主要根据第 31届国际地质大会上关于花岗质岩浆作用与成矿 ,花岗岩系统及元古宙岩石圈过程 ,玄武岩 ,碱性侵入体的成因与侵位 ,碳酸岩、金伯利岩、钾镁煌斑岩及相关岩石 ,造山带酸性与中性火山岩 ,火山作用等方面的发言、论文及摘要 ,结合其它资料 ,对近些年来国际、国内火成岩石学领域的新进展和研究动向进行讨论。认为从 2 0世纪末到 2 1世纪初 ,在地球动力学和全球变化的总框架下 ,在人类对资源、环境、减灾重大需求的推动下 ,火成岩石学在地球物质科学、岩石探针、大火成岩省事件与超级地幔柱、地幔动力学。

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.
