Progressive Dolomitization Of Florida Limestone Recorded By Alkaline Earth Element Concentrations In Saline, Geothermal, Submarine Springs, Johan Schijf, Robert H. Byrne

Studies in the late 1970s revealed that the effluents of saline, geothermal, submarine springs on the West Florida Shelf have compositions nearly identical to seawater, except for distinct Ca enrichments and Mg depletions, probably resulting from dolomitization. During annual visits between 1996 and 2003 we collected high‐purity effluents from four submarine springs and from Warm Mineral Springs (WMS), which is located on land. Filtered effluents were analyzed for major ions and for Sr and Ba. These analyses confirm the seawater‐like composition of the effluents as well as the Ca enrichment and Mg depletion. The alkaline earth elements Sr and Ba, …
