摘要
中国大陆壳体由华夏壳体、西域壳体和藏南壳体构成。本文给出这３个壳体的质量模型和元素丰度，并从成矿元素，热源元素和镧系元素方面讨论它们的区域丰度特征。结论认为，它们的地球化学背景是各不相同的。
The continental crustobody of China are composed of three regional crustobodies, i.e. the Cathaysian crustobody, the West China crustobody and the South Tibet crustobody. Their mass models and element abundances are given out in this paper. And their regional characteristics are discussed with the abundance values of metallogenic elements, heat source elements and lanthanides. The conclusion is that their geochemical backgrounds are quite different from each other.
