雾灵山A型花岗岩系的矿物学特征及成因意义

雾灵山杂岩体由似斑状碱长正长岩及其中的岩石包体、碱性石英正长斑岩、碱性石英正长岩等岩石组成，是冀北地区白垩纪岩浆活动的代表。本文以岩相学工作为基础，讨论了这些岩石中主要造岩矿物的结晶顺序和共生关系，报道了它们的成分特点和演化趋势，推测了不同矿物结晶时的温度、压力、氧逸度、含水量等生成状态和条件，并探讨了由它们所反映出的岩浆演化历史、特点和岩石成因系列归属问题。

Rock-Forming Minerals and Magmatic History of Evolution and Crystallization of Wulingshan A-type Granitic Complex

Wulingshan A- type granitic complex,composed of porphyaceous alkali-feldspar syenite,rock inclusion occured in above rock,alkali quartz syenite-porphyry,alkali quartz syenite and alkali-feldspar syenite porphyry,is a representive product of Cretaceous magmatism in northern China,Based on data of petrography we discuss crystalline sequence and pargenesis relationship of major rook-forming minerals oc-cured in above rocks,report composition of major elements and chemical trend of evo-lution in these minerals,estimate condition of temperature,pressure,oxygen fugacity and water partial pressure in diagenetic process,and infer history of crystallization of major rock-forming minerals and characteristics of evolution during magmatism.
