相山新元古代变质岩由泥砂质变质岩和斜长角闪岩组成。本文对其已变质为十字石榴云母片岩、石英片岩和变粒岩的泥砂质岩石进行了地球化学研究，并研究了某些元素间存在的线性关系。这套泥砂质岩石相对富ＳｉＯ２、ＴＦｅＯ、Ａｌ２Ｏ３、Ｋ２Ｏ，贫ＭｇＯ、ＣａＯ、Ｎａ２Ｏ；总稀土含量高，轻稀土高度富集，负Ｅｕ异常较强。其主要岩类岩石化学和地球化学特征说明它可能形成于大陆岛弧构造环境，形成的时代为前震旦纪
Xiangshan Neoproterozoic metamorphic rocks are composed of muddy metamorphic rocks and amphibolite. In this paper, the geochemical study of the metamorphic Paleo-pomegranate mica schist, quartz schist and granulite of granulite has been carried out and the linear relationship between some elements has been studied. The siltstone is relatively rich in SiO2, TFeO, Al2O3, K2O, poor MgO, CaO, Na2O; high total rare earth elements, highly enriched in light rare earths, strong negative Eu. The petrochemical and geochemical characteristics of its main rocks indicate that it may be formed in the continental island arc tectonic environment and the formation of the Pre-Sinian
