Additionally, limestone can be formed through the presence of calcium carbonate. The purity of limestone can be found through the color and darkness of the rock, in other words ...Importantly, limestone bedrock tells geologists that at the time of formation, that area was a shallow sea. Limestone formed in these environments because its main composition is calcium carbonate, which was deposited when shells and pieces of shells from small shallow water invertebrates settled down to the sea floor.

It must be 50% calcium carbonate by weight, in the form of calcite. Limestone may also contain other materials, like particles of quartz, feldspar, clay, and more. The presence of these additions is what gives limestone its unique colors and patterns, and which minerals are in limestone depends on where it is sourced from.
