It's hard to pull Mg out of seawater, and we know that minerals with it, like dolomite, form along a redox profile. But why?
We decided to look at it a bit differently - with electrochemistry!
What we think is going on is a process called “proton-driven cation pumping,” which pulls out the Mg and pushes it (and Ca) into the mineral phase, driven by the electrical potential gradient.
