(a, c)温度—SiO₂; (b, d)温度—晶体百分比；(a)和(c)图中数字代表当前温度下结晶矿物的总含量； plag：斜长石;tmte：钛磁铁矿;olivine：橄榄石;augite：普通辉石;opx：斜方辉石;garnet：石榴子石;hbde：角闪石；数据来源:(a)和(b)数据来自参考文献[43];(c)和(d)数据来自参考文献[44]；(a)和(b)展示Sisson等^[43]在200 MPa、水饱和（质量百分含量为4.9%）条件下的玄武岩相平衡实验的结果;(c)和(d)展示Muntener等^[44]在1.2 GPa、富水（质量百分含量为5.0%）条件下玄武岩相平衡实验的结果

Fig.4. Plots of the phase-equilibrium experiment results for two types of basalts
(a, c) Temperature versus SiO₂; (b, d) Temperature versus Crystal percentage; The figures in the plots (a) and (c) represent the total amount of crystallization minerals at the current temperature. plag：Plagioclase; tmte：Titanomagnetite; olivine：Olivine; augite：Augite; opx：Orthopyroxene; garnet：Garnet; hbde：Hornblende. Data of plots (a) and (b) from reference [43]; Data of plots (c) and (d) from reference [44]. Plots (a) and (b) show the result of basalt phase-equilibrium experiment at 200 MPa, water saturation (4.9 wt.%) by Sisson et al.^[43]; Plots (c) and (d) show the result of basalt phase-equilibrium experiment at 1.2 GPa、high water content (5.0 wt.%) by Muntener et al.^[44]
