Physical-chemical formation of stalactites/stalagmites. what promotes the formation/growth of these structures?

I know, or think I do, the basic idea behind these natural structures, as from what I know they form due to water dripping from the top leaving a salt deposit behind. But started to wonder about...

You could use the Henry model. It is the simplest adsorption model and usually for low pressure or low concentration.

n=Kp or n=kc

Mehmet Can Dal

In an effective adsorption, Henry's law does not apply. As the capacity reaches saturation, moves away from the linear correlation

the best by far langmuir.I found a new linear equation of the harkins-jura model. Better than Langmuir. I am preparing for publication. If I don't forget after it's published, I'll write the formula here
