a sedimentary rock commonly composed of quartz sand grains
cemented together by silica, calcite, iron oxide, or other
mineral substance, Depending upon the amount and character
of the cementing agent, sandstones may be almost any color.
In Florida, the colors generally range from almost pure
white through shades of yellow, orange, red and brown.
Occurrence: The occurrence
of sandstone is limited in Florida largely to the red sandy
clay formations of the central peninsula and northwestern
part of the State. it generally occurs as thin discontinuous
layers or small nodules though it has been observed in beds
up to 10 feet thick.
