A simple formulation to calculate the sequence and rate of salt precipitation in a brine? Is there a simple formulation to estimate the rate of salt precipitation in a brine given its ion concentrations and the evaporation rate? 

For example: if we know the concentrations of Cl−, Na+, Mg2+, SO42−, Ca2+, K+ of a sea-water brine at a known temperature T, what salt(s) and how much of each will precipitate for a given evaporation rate E (assuming time enough for equilibrium)?
Can you refer to a concise text-book or article?

I need something that goes beyond the simplistic saturation concentration concept (i.e., prescribed limit for diluted salt concentration). The effects of life in the solution can be dismissed.
Here is a link to a hydrochemical consultant, Dr. C.A.J. Appelo, and the public-domain software FREEQC.

This link leads to an example of salt precipitation rates when evaporating sea water.

The formulation used is detailed in a second manual
