Polymorphic Nature of Iron and Degree of Lattice Preferred Orientation Beneath the Earth's Inner Core Boundary

Mattesini, M.; Belonoshko, A.B.; Tkalčić, Hrvoje


Deciphering the polymorphic nature and the degree of iron lattice‐preferred orientation in the Earth's inner core holds a key to understanding the present status and evolution of the inner core. A multiphase lattice‐preferred orientation pattern is obtained for the top 350 km of the inner core by means of the ab initio based Candy Wrapper Velocity Model coupled to a Monte Carlo phase discrimination scheme. The achieved geographic distribution of lattice alignment is characterized by two regions...[Show more]
