How Is Limestone Made?

Limestone can be formed as a result of evaporation, as is the case for stalactites and stalagmites in caves, or through the accumulation of calcium carbonate in marine environments. Limestone is either a biological or a chemical sedimentary rock, depending on its method of formation.Read more≫

From What Is Limestone Made?

Limestone is a sedimentary rock that is at least 50 percent calcium carbonate, and is found in nature in the form of the mineral calcite. Calcium carbonate has the molecular formula CaCO3. The formation of limestone can occur either through evaporation or the accumulation of shells from dead organisms like oysters in a marine environment.Read more≫

What Color Is Limestone?

Limestone is a sedimentary rock that is usually white in color, as it is largely composed of calcium carbonate. Limestone can be colored by impurities, however; iron oxide can make limestone red, brown or yellow, while carbon can make it gray, black or blue.Read more≫
