Phase-transition-induced texture of post-perovskite and D'' discontinuity

Magnesium silicate post-perovskite phase (PPv) is widely regarded as the most likely candidate to explain seismic anomalies observed at the Earth’s D’’ discontinuity. However,...硅酸镁后钙钛矿相（Magnesium silicate post-perovskite phase, PPv）被广泛认为是解释地球D''间断面处观测到的地震异常的最具可能性的候选矿物相。然而，
