Corrigendum: Polymerized 4-Fold Coordinated Carbonate Melts in the Deep Mantle

A Corrigendum on
Polymerized 4-Fold Coordinated Carbonate Melts in the Deep Mantle

by Sanloup, C., Hudspeth, J. M., Afonina, V., Cochain, B., Konôpková, Z., Lelong, G., et al. (2019). Front. Earth Sci. 7:72. doi: 10.3389/feart.2019.00072

In the original article, there was a mistype in Equation (2) used to simulate the experimental C-O contribution on g(r) (Figure 3B).

A correction has been made to Section 2, Density Measurements, equation 2:

$\begin{array}{ll}g(r)=\frac{c_C{c}_O{K}_C{K}_O}{Z_{tot}^{2}n{S}_{\infty }}\frac{A}{\sigma \sqrt{2\pi }}exp\left(-\frac{{(r-d)}^2}{2{\sigma }^2}\right)& (2)\end{array}$

where c_C and c_O are the atomic proportions of carbon and oxygen, K_C and K_O are defined as the average effective atomic number over the experimental q-range (Eggert et al., 2002) and calculated using form factors from Hajdu (1972). Other parameters are as defined in the article.

The authors apologize for this error and state that this does not change the scientific conclusions of the article in any way. The original article has been updated.
