What is it and
where was it formed?
mostly found in
sedimentary rock. Calcite turns into the
rock called limestone. Some limestone is made when sea
creatures die and their skeletons and shells fall to the
bottom of the ocean. They pile on top of each other, push
on the lower layers, and the pressure makes limestone.
All limestone starts in water. There are places in the
middle of the United States where there used to be a sea.
The water has been gone for millions of years. Even though
itís dry now, limestone can be found there. If you add
pressure and high heat to limestone, it changes into
How and where
is it mined? Calcite is mined
underground mining. If the calcite is
not far underground, then quarrying is used. If it is too
far underground for quarrying to work, then underground
mining is used. It is found in New Jersey [Franklin], Tennessee,
Illinois, and other states of the U.S.; Mexico, Germany,
India, England, and other parts of the world.
What is it
used for? Calcite/limestone is
used for making glass, paper, photography, statues,
building, and animal food. The Ancient Egyptian Sphinx
[below] is made of limestone.
