What is Limestone? (with pictures)

What is Limestone? (with pictures)The key mineral present in limestone is calcium carbonate, but the rock is often mixed with other mineral impurities. These impurities can dramatically alter the texture of the rock, along with its color. As an example of the diversity of limestone, both chalk and marble are forms of limestone, even though these two rock varieties look and feel very different. In the case of chalk, the rock is ...
