Introduction
The auxiliary material for this article consists of 6 tables. TS01 and TS02 detail in tabular form
aspects that were discussed within the “Results” text of the main article. TS01 displays the
model reaction progress and TS02 displays variations in mineral product as related to initial
parameter variation. TS03 and TS04 contain the fluid speciation data of representative samples
from the analyses of experimental fluids. This information was calculated with Geochemist’s
Workbench (GWB) from the fluid data presented in Table 4 of the main article. TS05 and TS06
are mineral saturation indices calculated from the speciation data in TS03 and TS04,
respectively.
