Six kinds of basalt ores taken from different areas were selected, and the composition and the lithofacies and mineral pha-ses before and after melting were analyzed respectively to reveal the influence on the high temperature melting of ore. The results showed that SiO2 is the main component in the basalts, and determined the physical and chemical properties of basalts.Natural basalt ores are mixtures of various crystal minerals.The crystals were transformed into amorphous glass after melting at 1500℃.It is found that the components of basalts is crucial in governing the melting at high temperature, and the mineral phase can also have certain effect.An interactive effect is expected for the high temperature melting from individual mineral.%选取不同地区的6种玄武岩矿石作为原料,分别对其组分及熔融前后的岩相、矿物相进行分析,并研究组分、矿物相对矿石高温熔融的影响.结果表明:玄武岩的主要组分为SiO2,含量最高,对玄武岩的物理化学性质有较大的影响.天然玄武岩矿石为各矿物相混合晶体,经1500℃高温熔融后晶体消失,转化为非晶体玻璃态.在玄武岩高温熔融的影响因素中,各组分及含量是主要因素,矿物相是次要因素,各矿物相对其高温熔融过程有交互影响.
