Due to an unfortunate error, the equations [Eq. (25) on page 4, Eq. (35) on page 9, Eq. (37) on page 10 and Eqs. (38)–(40) on page 11] were published incorrectly. The correct version of equations is given below.

The ideal contribution to the activity of sudoite is

$$ a_{\text{sud}} = 64\left( {x_{\text{Al}}^{{{\text{M}}23}} } \right)^{2} \left( {x_{\text{Mg}}^{{{\text{M}}23}} } \right)^{2} x_{\text{Va}}^{{{\text{M}}1}} x_{\text{Al}}^{{{\text{T}}2}} x_{\text{Si}}^{{{\text{T}}2}} $$

The equilibrium constant expression

$$ - \ln (k) = \frac{{\Delta H^{0} + (P - 1)\Delta V^{0} }}{RT} - \frac{{\Delta S^{0} }}{R} $$

Geothermometer Chl(1): (ΣFe = Fe²⁺ + Fe³⁺)

$$ - \ln (k) = \frac{172341}{RT} - \frac{315.149}{R} $$

(37)

$$ T_{\text{Chlorite}} \,(^\circ {\text{C}}) = \frac{172341}{ - R\ln (K) + 315.149} - 273.15 $$

(38)

Geothermometer Chl(2): (ΣFe = Fe²⁺)

$$ - \ln (k) = \frac{203093 + 4996.99P}{RT} - \frac{455.782}{R} $$

(39)

$$ T_{\text{Chlorite}} (^\circ {\text{C}}) = \frac{{203093 + 4996.99P\,({\text{kbar}})}}{ - R\ln (K) + 455.782} - 273.15 $$
