With a crystalline brine-source being reasonably ruled out, I was wondering if you had any thoughts as to the origins of the ionic content/salinity?

Interesting study that should provide important results on fluid and microbial community circulation through crystalline basement rocks. I had a similar question to Oliver's: you mention cation/anion chemistry of springs is distinct from surface waters and shield type brines. Are there any other groundwaters (i.e., potential fluid sources) that have similar major ion chemistries?

Can you expand on why the water chemistry (Cation/anion) of Saratoga Springs does not support mixing with a Precambrian crustal brine source?

Thanks for the nice ppts! It is intriguing to see that linear line above the GMWL! I have two questions: 1. Can you clarify cation/anion data further for source differentiation? So the cation/anion composition between the Saratoga Springs fluids and the Precambrian crustal brine waters are very different (i.e., no mixing scenario is derived)? 2. Are there any sample candidates to fill the gap between the Yellowknife end member and other samples to further strengthen this linear line? Thanks!
