Evaluating The Core: The prospect of geodes

Kira Moor, Rebekah Ingram


This paper analyses the legitimacy of some of the science behind the movie The Core. The feasibility of the formation of large amethyst geodes in the Earth’s mantle as seen in The Core is investigated by calculating the pressure in the mantle and analyzing the effect of mantle temperature on amethyst crystallization. The analysis shows it to be extremely unlikely that geodes exist in the lower mantle.
