Answer:
Evaporite minerals formed from restricted open ocean circulation with high evaporation rates
Step-by-step explanation:
Salts like halite and gypsum are called evaporites.
Evaporites are chemical sedimentary rocks that forms when water in a basin(oceans, lakes) are restricted to flow and evaporation causes precipitation of the minerals dissolved in the water.
Halite and gypsum form insolube precipipate that accumulates over a long period of time in such an environment. The formation of evaporite largely depends on the dissolved load of a sediment and the environment of depositon of the load.
