龙游角门橄榄岩山露于古老变质岩中．与围岩间的接触关系尚不清楚，但根据岩相学上矿物的平衡共生关系、岩石的矿物化学组成和角门橄榄岩及与之相关的花岗岩、金云母岩的微量元素地球化学特征．该橄榄岩很可能是富含流体组分的岩浆侵人而形成的，其形成的构造背景为具俯冲带性质的活动大陆边缘，富流体相的岩浆是由于其地幔源区受到了来自俯冲带的流体所交代的结果。
Longyou angle door olive rock exposed in the ancient metamorphic rocks. The relationship with the surrounding rock is unclear. However, according to the balanced symbiosis of minerals in petrography, the mineral chemical composition of rocks and the trace element geochemical characteristics of keratolithic peridotites and related granite and phlogopites, The peridotite is likely to be formed by intrusion of fluid-rich magma. Its tectonic setting is characterized by active continental margins with subduction zones. The magmatic fluids of the fluid-rich phase are due to the subduction of the mantle from the subduction zone Of the fluid account for the results.
