花岗岩研究的最新进展及发展趋势

摘    要:本文重点讨论了花岗岩成因类型及其同地球动力学体系的关系、花岗岩形成时的物理化学约束条件、产生花岗岩的热源、花岗岩的定位机制及花岗岩同成矿作用的关系。地球化学和其他证据表明,花岗岩浆一般说是地壳和地幔物质混合的结果,实际上可能存在一种地幔源与地壳源之间的连续谱系。花岗岩研究下一步将向何处去?同地球动力学相关联,花岗岩形成时的热源、岩浆混合和岩浆上升、定位的机制,可能是在最近的将来解决花岗岩问题的关键。

关 键 词:花岗岩类型,岩浆混合,热源

Abstract:This paper discusses granite types and their relationship with geodynamics,physical-chemical conditions of formation of granites,the heat sources which producedgranites,the emplacement mechanisms of granites and the relationship of this last with themineralization process. Geochemical and other evidence shows that in most cases granitemagmas are the result of crust/mantle mixing.It is possible that a continuous series ofgranites resulting from crust/mantle mixture exists.The keys to solving granite problemsin the future include connections with geodynamics,identification of heat sources and themechanisms of magma mixing,ascent and emplacement.
Keywords:granite types  magma mixing  heat source
