Evaporites are formed by evaporation of restricted bodies of water at the Earth's surface.
Although all water bodies on the surface and in aquifers contain dissolved salts, in order to form minerals from these salts, the water must evaporate into the atmosphere in order to precipitate the minerals.
In order for this to happen the water body must enter a restricted environment where water input into this environment remains below the net rate of evaporation. This is usually an arid environment with a small basin fed by a limited input of water.
Most evaporites are derived from bodies of sea-water, however evaporites can be created by evaporation of fresh water sources such as rivers, by aquifers or even by rainfall.

ummm...that might be a bit of a stretch...where as yes they are derived from water, but it is the evaporation caused by the sun which leads to them being deposited

Yes, I can't think of any other liquid that would leave them behind when it evaporates.
