陈蔡群斜长角闪岩的基本组成矿物是斜长石和角闪石，不同样品中还可出现透辉石、黑云母、石英和碱性长石等。大多数斜长角闪岩显示石英拉斑和橄榄拉斑系列的特征，个别属于钙碱性系列。其稀土元素配分曲线显示不同程度的ＬＲＥＥ富集特征，指示斜长角闪岩原岩在成岩过程方面的多样性。根据微量元素蛛网图的斜率和Ｎｂ、Ｔａ异常情况以及Ｚｒ－ＴｉＯ２相关性，斜长角闪岩主要分成岛弧和洋岛两种类型，指示陈蔡群的原岩形成于洋内俯冲或洋陆俯冲的环境。龙游八都群斜长角闪岩呈ＭＯＲＢ的地球化学特征，与陈蔡群斜长角闪岩形成鲜明的对比
The primary constituents of the plagioclase amphibolite in the Chencai Group are plagioclase and amphibole, and diopside, biotite, quartz and alkaline feldspar may also occur in different samples. Most of the plagioclase amphiboles show the characteristics of quartz pullulans and olive pullulan series, some of which belong to the calcium-alkaline series. The REE distribution curves show different degrees of enrichment of LREE, suggesting that the amphibolite protoliths diagenetic process diversity. According to the slope of the trace element cobweb and the anomalies of Nb and Ta and the correlation between Zr and TiO2, the amphibolite is mainly divided into two types: island arc and oceanic island, indicating that the original rocks of Chencai Group formed in intracontinental subduction or oceanic subduction environment of. The geochemical characteristics of MORB in the amphibole-amphibolite from Longyou are similar to that of the plagioclase amphibolite in the Chencai Group
