As it is implied about halite formation environment or salt, these rocks are related to sea and or in some basins to lands. Suitable conditions and positions is related to evaporate deposits and totally or around continental plateau and or inside of cratonic basin (such as Michigan which is situated inside of stable cratonic apron) is provided and in reality mentioned condition is dominant is two following environments and we can expect evaporate sediment and productions.
A- Sabkha environment with transitional subsiding including continental and coastal sabkha.
B- Marine environment (lagoons and related gulf to sea)
Type and composition of deposits in lacustrine environments with its rocks in these lakes have close relation. If ratio of calcium is high rather sodium and gypsum will deposit and if chlorine ion is enough halite or salt will be presented and gypsum will precipitate. If chlorine ion is enough halite or salt will precipitate but if there is in an lake environment with much salt and we conclude there are abundant salt around sedimentary basin that it is transported as a result of leaching and transportation to lake.
