Summary
[edit]DescriptionBlowhole in aragonitic limestone (just east of The Notch, southern margin of San Salvador Island, Bahamas) 15 (16040398085).jpg |
Blowhole in aragonitic limestone. Openings to the land surface along rocky shores that are above sea caves or smaller cavities are called blowholes. As waves crash in, air and water are forced upward. The rocks at this locality are eolian aragonitic calcarenite limestones - they are composed of sand-sized grains of CaCO3 deposited in an ancient wind-blown sand dune environment. Stratigraphy: Cockburn Town Member, Grotto Beach Formation, lower Upper Pleistocene, 119-131 ka Locality: just east of The Notch, southern margin of San Salvador Island, Bahamas |
