摘    要:近 10多年来 ,人们已认识到大多数花岗岩浆的发育和演化受岩石圈上地幔作用过程的制约 ,开创了把壳幔相互作用研究与花岗岩形成演化紧密结合的新方向 ,这个新的研究方向的科学前沿主要是花岗岩形成与大陆生长和深部过程的关系 ;花岗岩形成的深熔作用和热源以及花岗岩的成因类型与构造环境。这些前沿研究试图从大陆生长及大陆动力学的层次去认识花岗岩成因 ,以期能建立起一个它们之间相互关联的框架 ,并进一步通过这一框架追索它们形成时热能传递的机理及其体制。因此 ,研究花岗岩不仅可以获得花岗岩物质来源和构造环境的信息 ,而且可以获得壳幔物质运动的状态、过程、动力学等问题的本质、深部能量 (热能 )的传导、转化的重要信息。探索和解译这些信息 ,对于认识大陆生长具有“纲举目张”的作用 ,是解决当今大陆地质演化 ,建立大陆动力学关键问题之一 ,是继花岗岩物质来源、构造环境研究的花岗岩研究的第三个里程碑的开始 ,因而具有重要的战略意义。

关 键 词:花岗岩  大陆地壳生长  深熔作用  构造环境

Abstract:In the last ten years, people has realized that the formation and the evolution of granitic magma are controlled by the process of the action of lithosphere upper mantle, and has inaugurated a new study direction in which the crust-mantle interaction is closely combined with the formation and evolution of the granitic magma. The scientific frontiers of this new direction primarily are: the relationship between the granite formation and the continent growth and the deep process in lithosphere; the granite anatexis and the heat source in the granite formation; the relation of genetic type of granite to the tectonic environment. These frontiers try to understand the granite genesis from the conceptions at the level of continent growing and continent dynamics, and it is hoped to establish a frame that associates them, and through this frame further to trace the mechanism and the region of the thermal energy transfer during the formation of the granite. Therefore, the study of granite cannot only provide the information of granite material source and tectonic environment, but also can acquire the important information of the essential aspects of crust-mantle material movement state, process, dynamics, etc., and of the conduction and convection of energy (thermal energy) in the depth. The study and interpretation of these informations can take effect of lucid exposition of essential points for understanding the continent growth, and is one of the key problems for resolving the nowadays issue of continent geological evolution, and for establishing the continent dynamics. It can be regarded as the beginning of the third milestone in the granite research, after the researches of the granite material source and the tectonic environment; thus it has important strategic meaning.
Keywords:granite  continent growth  anatexis  tectonic environment
