摘　　要：花岗岩类化学元素丰度研究是花岗岩类地球化学和地壳丰度研究的一项重要内容,一直为国际上所关注,并有很多学者先后发表了不同的花岗岩类化学成分和元素丰度的数据,但迄今为止世界上还没有花岗岩类地球化学图的出版。本文以中国56种元素花岗岩类地球化学图为基础,探讨了中国大陆花岗岩类各元素地球化学图所展示的多元素的区域分布特征、空间分布规律和分布模式。结果显示,花岗岩类各元素的空间分布模式与中国花岗岩类的分布和特征密切相关。花岗岩类地球化学图能够清晰地反映出花岗岩类化学成份的空间变化规律和特征。The abundance of chemical elements in granitoids is an important research content of granitoids geochemistry and crustal abundance, and has been paid attention to by the international. Many scholars have published various data for granite chemical composition and abundance of elements, but so far the world has no granitoids geochemical map published. Based on the geochemical maps for 56 elements in granitoids of China mainland, which have been compiled using actual analytical data of 767 composited samples of granitoids, the regional distribution characteristics, spatial tendencies and distribution patterns that are presented on different element geochemical maps are discussed in this paper. The results showed that, the spatial distribution of various elements concentrations in granitoids are closely related to the distribution and characteristics of Chinese granitoids. Granitoids geochemical maps can clearly reflect the spatial variation and characteristics of granitoids in the chemical composition of.
