A salt is the product of the reaction between an acid and a metal.
Rock salt and gypsum are not varieties of dolomite.
Gypsum is also a salt and of course it is waterproof and water tight.

gypsum rock often forms when salt evaporates just like h2o 555 it does to that what i think 89392

rock salt and rock gypsum
Rock salt and rock gypsum are predominately the minerals halite and gypsum respectively. Quartzite is also predominately the mineral quartz.
It will depend in what is in the water, in general it will be the solids that have been dissolved, but they will come out as crystals if evaporated slowly. in general it will be salt and/or limescale (calcium carbonate) as they are easily soluble
Rock salt, rock gypsum, and sometimes limestone.
