Regional geographical and mineralogical divisions of Atlantis Bank. Dashed gray lines divide the northern, eastern, southern, and western regions as discussed in the text. Locations of samples selected for mineral analysis shown as red stars. Blue circles show location of oolitic limestones. Two-thousand-five-hundred-meter contour outlines the likely depth for sub-aerial erosion and shelf formation based on oolitic limestones sampled by dredging and diving. Two-thousand-meter contour shown for reference, whereas 900 m contour (in red) outlines the wave-cut platform at the crest of Atlantis Bank (see Fig. 5)
