Limestone rock formation
Two of the most widely used classifications are those of Folk (1959,1962) and Dunham (1962). Both classifications subdivide limestone s primarily on the basis of matrix content. Most limestone s are classified by Folk allochemical Rock s if they contain over l0% allochems (transported carbonate grains). Based on the percentage of interstitial ...Limestone. Limestone ( calcium carbonate CaCO3) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of CaCO3. Limestone forms when these minerals precipitate out of water containing dissolved calcium.
