RUSSIAN JOURNAL OF EARTH SCIENCES, VOL. 19, ES5006, doi:10.2205/2019ES000677, 2019 Figure 3. Fluid pressure as a function of the weight fraction of the reacted silica (in the initial mixture dolomite plus silica) is calculated with simplified micromechanical model. We assume that decarbonatisation reaction follows equilibrium trajectory $P = P_{\mathrm{eq}} (T)$. Initial porosity ($\varepsilon_0$) filled with CO$_2$ fluid at $P_0= 2$ GPa is indicated in legend. Thick dashed line depicts diamond stability boundary. Copyright 2019 by the Geophysical Center RAS. Generated from LaTeX source by ELXfinal, v.2.0 software package. |
