Well, when that ice melted, and ended up in the oceans, wouldn't that have lowered the concentrations as well?
Yep. When salt water freezes the salt is excluded from the ice crystals. The build up of ice would have increased the salinity of the oceans, and the opposite would have happened once the ice melted.
In fact, it is this freeze/thaw cycle that powers ocean currents. As ice freezes at the poles it produces dense, cold water due to it's temperature AND it's salinity. This mechanism is part of the thermohaline ocean currents (notice the name thermo-heat and haline-salt).

Re: Continued discussion from another thread.
So there are two issues concerning the haltite: What processes formed them in the past, and why aren't we witnessing them right now ? After all, the laws of chemistry didn't change since back then.
That is a very interesting statement coming from a YEC. Can you remind as again about how accelerated nuclear decay works?
I know it is off topic here, but please remember that you made this statement for other discussions.
Now, you claim that this Salt deposits comes from the oceans, despite any evidence that chemistry allows for such depositions in our oceans today. Yet you still claimed that it happened in the past.
If this involves evaporation of terrestrial waters this still casts doubt on steady input into the oceans. Either way, you have either a fluctuation input or a fluctuation output which negates the use of salt concentrations as a reliable dating method.

Re: I call bullshit
No. I'm stating the fact that when inland seas evaporate, the water condensates into rain which only increases the rate of sodium being redeposited back into the oceans.
Have you checked the salinity of a fresh water river compared to the ocean? Last i checked the concentration of salt in the oceans is a lot higher than that found in rain water. The very fact that we find salt deposits that are NOT moving back into the ocean simply disproves your assertion.
