镁橄榄石（Mg2SiO4）冲击峰值压力为78至92吉帕斯卡的透射电子显微镜观察显示，镁橄榄石分解成一个组合的MgO加MgSiO3玻璃。这有力地支持了镁橄榄石在冲击压缩下的高压相是由于MgSiO3钙钛矿加MgO的组合的解释。
Transmission electron microscopic observation of forsterite (Mg2SiO4) shocked to peak pressures of 78 to 92 gigapascals revealed that forsterite breaks down to an assemblage of MgO plus MgSiO3 glass. This strongly supports the interpretation that the high-pressure phase of forsterite under shock compression is due to the assemblage of MgSiO3 perovskite plus MgO.
