title: Calcium and bromide contents of natural waters.
abstract: The linear relation observed in a log Ca++ versus log Brplot for subsurface Cl- waters is attributed to ultrafiltration by shale of sea water and fresh water that have passed through sedimentary rocks since their formation. Reactions between these solutions and sedimentary minerals, particularly dolomitization, must have contributed additional Ca++ to solution.
