Abstract Establishing the distribution of bromine in the chloride facies of marine evaporites aids in the reconstruction of the paleosalinities in evaporite basins and provides an important geochemical tool in the exploration for potash deposits. Detailed stratigraphic profiles of bromine distribution are also useful in resolving problems in correlation and in understanding some of the post-depositional processes that have occurred in the evaporitic rocks. Much work has been done on the geochemistry of bromine in the German Zechstein. A few of these workers are: Baar (1954, 1955, 1963), Boeke (1908), Braitsch (1962, translation 1971), Braitsch and Herrmann (1 963), D’Ans and Kühn (1940-1944), Herrmann ( 1 958), Kühn (1 955, 1968), Schulze (1960), and Schulze and Seyfert (1959). Examples of work done in Russia are by Ogienko (1959) and Valyashko (1956). In recent years, bromine geochemical work has been done by Baar (1966), Schwerdtner (1964), Schwerdtner and Wardlaw (1963), and Wardlaw (1964) in Canada; Holser (1966), Raup (1966), and Raup and others (1970) in the United States; and Hite (1974) in Thailand.
