Weak cubic CaSiO₃ perovskite in the Earth’s mantle

Autor: Immoor, J., Miyagi, L., Liermann, H.-P., Speziale, S., Schulze, K., Buchen, J., Kurnosov, A., Marquardt, H.

Cubic CaSiO₃ perovskite is a major phase in subducted oceanic crust, where it forms at a depth of about 550 kilometres from majoritic garnet. However, its rheological properties at temperatures and pressures typical of the lower mantle are poorly k
