| Abstract: | In this study, 1131 analytical samples were combined with 10364 igneous rock samples collected from the major tectonic units of china and sublected to analysis by 15 reliable analytical methods such as INAA, XRF, AA, AF, POL, COL, etc. The newest analytical methods were used for determinating some rare elements, including the Pt-group elements. Analytical qualities were monitored by the same certified refference materials. Meanwhile, 739average values of major compositions of 5191 samples were selected from non-sampling area in the western part of China. On the basis of our results, abundances of 10 major compositions and 68 trace elements of 11 acidic rocks, 19 intermediate rocks, 8 basic rocks and 4ultramafic rocks have been calculated. in this paper, we have preliminarily probed into the temporal-spatial distribution and geochemical characteristics of the elements in igneous rocks. |
