| 摘 要： | 对我国港边岩浆混合杂岩体进行了系统的地质学、岩石学和矿物学研究，并将其分解为偏酸性端元岩浆、基性端元岩浆、混合岩浆和非岩浆混合物４个单元．从不同的角度探讨了岩浆混合和分离结晶作用同时发生对岩浆混合岩成分的制约，提出存在化学和机械两种岩浆混合方式，证明了它们与基性岩浆的侵入一起构成一个连续的岩浆作用序列．最后，在野外地质研究的基础上，结合端元岩浆起源和混合岩浆结晶ｐ－Ｔ条件的估算及端元岩浆形成构造背景的判别综合提出港边岩浆混合杂岩体的构造－岩浆模型

| Abstract: | Gangbian magma mixed complex body was systematically researched in geology, petrology and mineralogy. It was divided into four units: partical acidic and basic end member magma, magma mixed and magma unmixed matter. The article respectivelly investigated simultaneously combined magma mixing and fractional crystallization constrained on composition of the magma mixed rocks, and suggested chemical and physical styles for the magmatic mixing. It also confirmed that they constitute a continuous ordered series with the intrusion of basic magma. Finally, a tectonomagmatic model of Gangbian magma mixed complex body is synthetically proposed based on field geological study, combining p-T condition of calculation of origin of end member magma and crystallization of mixed magma and discrimination of the tectonic setting. |
