花岗岩大地构造研究的若干重要问题

宇宙星球中只有地球发育花岗质岩石及广义的花岗岩，它是大陆最主要的组成。因此，花岗岩在固体地球科学研究中具有举足轻重的意义。对此，作者提出花岗岩大地构造，其基本研究内容可概括为物理特性（构造）、物质组成（岩石地化）和年代学三大方面。文章在已有的初步论述基础上，进一步阐述了以下若干研究方面的进展、问题和发展方向:花岗岩岩石组合及其构造背景与环境厘定；花岗岩演化及其构造环境与演化（构造过程）；花岗岩变形、壳内流变及构造动力学意义；花岗岩深部物源填图与造山带及地壳生长。花岗岩大地构造是从花岗岩角度，探索解决大地构造问题，丰富大地构造研究内容，是当今地球科学学科交叉、融合发展的必要。 

SOME IMPORTANT ISSUES IN THE STUDY OF GRANITE TECTONICS

In the universe only the Earth develops granitic rock, which is the most important component of the continent. Therefore, granite plays an important role in solid earth science research. In this regard, the author proposes the basic research content of granite tectonics can be summarized as physical characteristics (structure), material composition (rock geochemistry) and chronology. Based on the existing preliminary discussion, this paper further elaborates the following research advances, problems and development directions:granite rock association and its tectonic setting and environment determination; granite evolution and its tectonic environment (structural process); tectonic dynamics of granite deformation and intra-shell rheology; the deep source mapping of granite and the growth of the orogenic belt and crust. Granite tectonics is to explore the problem of tectonics from the perspective of granite, and it enriches the content of geotectonic research. It is necessary for the interdisciplinary and integrated development of geoscience today.
