The comparative studies of lithogeochemistry for the volcano-intrusive complexes both from Jiulongzhang and from xiangshan reveal that the chemical compositions of the volcano intrusive complexes in the two areas are very close, and the trace element spidergrams and REE patterns basically coincide with each other. It is also shown that the two volcano-intrusive complexes have the same source features and the active continental margin tectonic settings. At the same time, it is found that, from early volcanic magma activities to later intrusive magma activities, the content of SiO2 and the Rb/Sr ratio decreased, on the contrary, the content of MgO and the ratios of K/Rb, Ba/Rb and LREE/HREE increased. It is shown that the hypabyssal or ultra-hypabyssal intrusives are not the products of the volcanic magmatic differentiation.

两地区的火山－侵入杂岩的岩石化学成分及其变化特点极为相近，微量元素蛛网图和稀土配分型式也基本一致，它们具有相似的岩浆过程和统一的活动陆缘构造背景；同时，从早期火山岩浆活动到晚期浅成－超浅成岩浆侵入活动，其w(SiO2)和w/w的值降低，而w以及w/w、w/w和w/w的值增高，晚期浅成－超浅成侵入岩与早期火山岩没有直接的分异演化关系。

It includes three conclusions. First, most undergraduates cherish Collectivism in China now. Second, there are nearly no relativities between the Collectivism and the individual characteristics of the undergraduates. Third, the relationships among the four factors are inerratic. Fourthly, the undergraduates'Collectivism has structures and arrangements. Besides, the complexity and the significance of the undergraduates'Collectivism are also illustrated. The incrementality and the emphases for the undergraduates to build up Collectivism are mentioned. As well, the specialty, the significance and the limitation of the study are included in this part.
