根据最近发现的具有CaCl2和α - pbo2结构的SiO2后辉石岩相，我们将Hugoniots的体系重新划分为初始石英、硅质岩、方英石、多孔硅质岩和熔融硅质岩。熔融石英、方英石和多孔粘土的计算Hugoniots表明它们向方英石过渡，然后熔融。晶体石英和硅质硅石的Hugoniots表明，晶石首先转变为硅长石，然后转变为CaCl2结构，最后转变为熔体。
[1] In light of recent discoveries of post-stishovite phases of SiO2, with the CaCl2 and alpha-PbO2 structures, we have reassigned the regimes along the Hugoniots for initial quartz, coesite, cristobalite, porous coesite, and fused silica. Calculated Hugoniots for fused silica, cristobalite and porous coesite indicate transition to stishovite, and then melt. Hugoniots for crystal quartz and coesite indicate that transition occurs to stishovite, then the CaCl2 structure and finally to melt.
