The Bahamas are largely built of limestone in one form or another. The land has a foundation of fossil coral, but much of the rock is oolitic limestone; the stone is derived from the disintegration of coral reefs and seashells.
Beneath the soil, the islands are composed of limestone rock and skeletal remains of coral fossils and other marine organisms.
The Bahamas lie within the zone of the northeast trade winds, and that has resulted in the preferential occurrence of islands on the eastern (windward) side of most banks. As a result of the glacioeustatic control of limestone deposition in the Bahamas, the lithostratigraphic units of Bahamian islands are also all stratigraphic units that are usually bounded by terra rossa paleosols.https://www.researchgate.net/publication/232381105_Chapter_3_A_Geology_of_the_Bahamas
