Salt in Oceans

Actually, what he needs to know is that we evolutionists are completely right about everything. Then he could admit that creationists are completely wrong about everything, and then he could move on.However, if, rather than taking my word for everything (which obviously he should) he chooses to look into it in slightly more detail, then it is only fair to him to say that saline giants and playas are in fact formed by completely different processes. 'Cos they are.

Your point, so far from being "obvious", seems both cryptic and unsupported.Clearly these marine evaporites constitute an output of salt because there they sit no longer contributing to the salinity of seawater. Because of not being dissolved in it.Now that is obvious.Edited by Dr Adequate, : No reason given.

I did wonder about this, but put it down to incoherence of expression rather than of the underlying thought.

Leaving aside the bit where you attempt to produce a quantitative argument without actually calculating any of the relevant quantities, could I draw your attention to the fact that the marine evaporites don't correspond to a higher rate of evaporation but a lower rate of mixing?The same amount of water would evaporate from the same amount of ocean whether it was or wasn't almost cut off from the main body of the ocean. But the precipitation of halite occurs only if it is. Unless, of course, and you may treat this as the purest conjecture, marine organisms can't tolerate high levels of salinity. I guess that would make the seas in question dead seas. Hmm ... that phrase rings a bell somehow ... and I'm sure it has something to do with salt ...Perhaps you could jog my memory. Perhaps you could provide a hypothesis as to how they did get there ... or is your claim just based on wishful thinking?Edited by Dr Adequate, : No reason given.

Not necessarily. They could just stay buried (Remember that there are still pre-Cambrian halite deposits knocking about). Or they could get subducted (a closing ocean basin is a good place for the formation of a saline giant and also a good place for subduction to occur).But I read Jason as saying that when evaporites are formed the amount of evaporation from the oceans increases, which increases the amount of rain on land, which increases the input of salt into the oceans, which somehow always manages to compensate exactly for the output through evaporite formation. Which is wrong for reasons that I've indicated.Perhaps if and when he comes back he could clarify this.
