Commercially, the Anastasia Formation is one of the three main stones of interest along the east coast of Florida. The formation contains quartz sand deposits, and crushed stone is used in road base and concrete aggregates, as well as chemical, agricultural, and metallurgical applications.
1 Μαΐ 2018 · The Florida Escarpment is a very steep slope where the seafloor plunges rapidly from the relatively shallow waters of the west Florida continental shelf – less than 100 meters (~330 feet) deep – to the abyssal plain of the deep Gulf, over 3,000 meters (~9,840 feet) deep.
When first cut, the rock is quite soft, but upon exposure to the atmosphere its surface become case hardened, making possible the development of sea cliffs in many outcrop areas. Among the most notorious geologic and sedimentary features of the Anastasia Formation are bioturbation with variable size burrows, laminated crusts, known as Caliche ...
Even the most active sea cliffs do not have their toes at sea level. The wave-cut bench characteristically slopes up to the toe of the cliff at elevations several feet above sea level.
South Florida lies within the "Southern Zone" of the coastal lowlands of the Coastal Plain physiographic province of the eastern United States. Most of this province originated from a combination of depositional and erosional processes associated with fluctuations in sea level during the late Pleistocene. Figure 1 shows the main physiographic ...
The term "Florida geology" should invoke visions of azure shallow seas, bustling coral reefs, hollow caverns beneath your feet, Ice Age animals traversing the ancient landscape, massive amounts of freshwater stored deep in our aquifers, and even sinkholes large enough to consume a building.
