Replace this text with your caption Figure 8. A plot of T($\Delta$_{47}) versus calcite $\delta$^{18}O. Superposed on the plot are two lines representing the composition of calcite in isotopic equilibrium for two scenarios. The first is mixing between a hot, formation water (T=100$^{\circ}$C, $\delta$^{18}O=+5‰_{VSMOW}) and a local groundwater (T=30$^{\circ}$C, $\delta$^{18}O=-4‰_{VSMOW}. The second is for precipitation from a fluid that cools from an initial temperature of 100$^{\circ}$C without any change in its isotopic composition. The data plot on, or close to the 2-component mixing model.
