Calcite Through much of Alabama's geologic past, the state was covered by ancient oceans, swamps, and other near-shore environments. The sediment left behind in these environments composes most of the state's bedrock: limestone, sandstone, shale, and chalk. All of these deposits are economically very important to Alabama.
