<P> Marine evaporites tend to have thicker deposits and are usually the focus of more extensive research . They also have a system of evaporation . When scientists evaporate ocean water in a laboratory , the minerals are deposited in a defined order that was first demonstrated by Usiglio in 1884 . The first phase of the experiment begins when about 50 % of the original water depth remains . At this point , minor carbonates begin to form . The next phase in the sequence comes when the experiment is left with about 20 % of its original level . At this point , the mineral gypsum begins to form , which is then followed by halite at 10 % , excluding carbonate minerals that tend not to be evaporites . The most common minerals that are generally considered to be the most representative of marine evaporites are calcite , gypsum and anhydrite , halite , sylvite , carnallite , langbeinite , polyhalite , and kainite . Kieserite ( MgSO ) may also be included , which often will make up less than four percent of the overall content . However , there are approximately 80 different minerals that have been reported found in evaporite deposits ( Stewart , 1963 ; Warren , 1999 ) , though only about a dozen are common enough to be considered important rock formers . </P>
