摘　　要：岩浆岩的成因研究在新时期需面向系统地球科学做些转变。单一的封闭体系下岩浆岩成因研究无法协调当前最新的高精度定年结果,也无法满足新形势下对地球系统科学和圈层相互作用深度研究的需求。岩浆系统的动态演变过程是当前岩浆岩研究的薄弱环节,也是恢复和构建岩浆系统、探索地壳结构与组成、进一步深入了解地球圈层相互作用机制等的重要内容。将岩石类型的定性描述纳入整个岩浆系统的研究中,将原位微区的时间-成分-温压分析与岩相学、全岩成分分析和实验模拟进行有机相结合,是未来研究圈层相互作用下的动态岩浆系统过程、不同批次熔体复杂相互作用、熔体成分演化,以及岩浆系统环境效应的有效途径。The studies on petrogenesis of magmatic rocks need a substantial paradigm shift in response to challenges on progresses in the systematic Earth science in new period.It is difficult for studying genesis of magmatic rocks under a single closed magmatic system to reconcile the latest new high-precision dating results and to meet the demand for in-depth research of the Earth system science and geosphere interactions under the new situation.The dynamic evolution process of magmatic system is the weak link in researches of magmatic rocks,it is also an important content for restoring and constructing detailed magmatic systems,exploring crustal structures and compositions,and further in-depth comprehensively understanding mechanisms for geosphere interactions throughout Earth's history.Therefore,the incorporation of the regular qualitative description of rock types into comprehensive investigations of magmatic systems and the organic combination of in-situ micro-scale timing-composition-temperature/pressure analyses and petrography,whole-rock geochemical analyses and experimental simulation and modeling are practical and effective ways to systematically investigate the dynamic magmatic system process under the geosphere interaction,the complicated interactions of multi-batches of melts,the evolution of melt composition,and the environmental effects of magmatic system in the future.
