Rocks. Rocks are interesting, right? Oh yes, they are. That’s why there are so many different types of rocks in the world: igneous, sedimentary, and metamorphic rocks. This post will take you through the different forms and names of these big-category rocks that are found in Florida.

Igneous Rocks

Igneous rocks form when magma cools and crystallizes. Extrusive igneous rocks form when magma exits and cools above Earth’s surface. Intrusive igneous rock forms when magma is trapped and cools below Earth’s surface.

Sedimentary Rocks

These rocks are formed due to the process known as weathering. Weathering breaks down rocks by physical and chemical means and can exist in solutions or as sediments. They’re formed from sediments that accumulate in layers known as deposition, which go through the process of lithification to cement the particles together.

Metamorphic Rocks

Metamorphic rocks form from pre-existing igneous, sedimentary, or earlier metamorphic rock when the rocks are subject to heat and pressure. The rock’s internal arrangement of atoms cause the rock’s chemical composition to change, thus forming it into metamorphic rocks.


A type of sedimentary rock found in Florida, peat is plant matter that is partially decomposed. Peat forms large and widespread deposits in the northern latitudes, where wet ground and plant growth supports its preservation. With burial, pressure, and heat, peat slowly turns into coal.

Industrial Sand and Gravel

Industrial sand is a term normally applied to high purity silica sand products with closely controlled sizing. Industrial gravel isn’t as nearly as precise compared to industrial sand. This mineral can be used to manufacture glass, abrasives, ceramics, chemicals, fillers, or filtration.


Sulfur rock is bright yellow, though the color may be altered if impurities are present. Sulfur is found in Florida by petroleum deposits, along with black petroleum. It’s soft, light in weight, and very brittle.

Ball Clay

These sedimentary clays are fine grained and are highly plastic. They’re used mainly in the manufacture of ceramic whiteware. Ball clays exhibit highly variable compositions and consist of a mixture of kaolinite, mica, and quartz, with each contributing different properties to the clay.


The mineral, cobalt, is a transition metal. It is used in magnets, high-tech turbines, and even in cancer treatments. The gamma radiation realeased by thise radioactive isotope can target tumors, particularly brain tumors that need precision treatment.


Cement is a manufactured material, and is formed through a closely controlled chemical combination of calcium, silicon, aluminium, iron, and other ingredients.


Titanium is one of the strongest elements. It’s able to resist corrosion and is lightweight. It appears in airliners and lacrosse sticks, body piercings and medical equipment and even sunscreen.


Asbestos is a set of six naturally occurring silicate minerals. It has been used in products, such as insulation for pipes and floor tiles. However, it is now recognized as a health hazard and its use is now regulated.

There are plenty of rocks and minerals found in Florida. As you can see, all of the above rocks are formed in the state of Florida. What other sorts of materials/rocks are found in your state?
