Table 9. Results from semi-quantitative X-ray analysis of Fakahatchee Strand-Gate 12 core

[Semi-quantitative analysis for quartz, calcite, dolomite, and aragonite. Other minerals, which may include potassium feldspar, plagioclase, muscovite, and (or) apatite, are assumed to represent less than five percent of each sample. Under Fm. (formation), T=Tamiami, U=unnamed. Results are to the nearest five percent and do not necessarily add up to 100 percent. “Trace” refers to minerals present but less than five percent of the sample]
