| 摘 要： | 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。

| Abstract: | The hornblende peridotite, outcropping in Longyou. Zhejiang Province. occurs within the metamorphic rocks with an old age (named the Longyou Group). The relationship between the peridotite and its wall rocks cannot be recognized now. However, according to the petrographically paragenetic equilibrium and mineral composition of the peridotite. and trace elemental geochemistry of the peridotite and related rocks, we suggest that this peridotite was probably formed by intrusion of a kind of fluid-rich magma. Its tectonic environment might be an old actively continental margin with a subduction zone, and the source mantle of the magma might have been metasomatized by the fluids derived from a subducted stab. |
