摘　　要：采用X线衍射分析(XRD)、X线荧光分析(XRF)、扫描电镜分析(SEM)和热重差热分析(TG-DSC),对取自黑龙江鸡西玄武岩样本(样品A)和辽宁阜新玄武岩矿物样品(样品B)的化学组成、表面形态及熔融析晶特性分别进行对比分析研究。研究结果表明:这2个样品主要矿物成分均为拉长石—钙长石,且均含有少量黏土类矿物;这2个样品表面形态相似,表面分层呈纹理状;样品B的酸度系数比样品A的小;样品B的熔融温度(1 291℃)、析晶温度(1 248℃)均分别比样品A的熔融温度(1 332℃)和析晶温度(1 262℃)低,表明在玄武岩纤维制备阶段工艺控制方面样品B较易实现。Chemical composition, surface morphology and melting crystallization characteristics of basalt mineral samples from Heilongjiang Jixi （sample A） and Liaoning Fuxin （sample B） were studied respectively by using X-ray diffraction （XRD）, X-ray fluorescence （XRF）, scanning electron microscopy （SEM） and thermo gravimetric-differential scanning calorimetry （TG-DSC） methods. The results show that the main mineral components of the two samples are labradorite-anorthite, which also contain a small amount of clay mineral The surface morphology of the two samples is similar with a textured surface layer. The acidity coefficient of sample B is lower than that of sample A. The melting temperature （1 291 ℃） and crystallization temperature （1 248℃） of sample B are lower than that of sample A （1 332℃ and 1 262 ℃）, which indicates that the sample B is relatively easy to achieve in the process of basalt fiber preparation control.
