Figure 5.

Three different amorphous components (a) Portage [Morris et al., ²⁰¹⁴[, (b) Cumberland, and (c) John Klein, reacted with GPW at 10°C. For compositional details, see Table 2. The results of these runs are also plotted on the clay ternary (Figure 8). The Fe oxide in Figure 5c is goethite. W/R is the ratio of incoming fluid with reacted rock.
