Generally speaking, its crushing and tensile strengths are greater than the oolitic limestones and its appearance shows greater variety in texture. Limestone is a carbonate sedimentary rock that consists predominantly of calcite [CaCO 3].Limestones are the commonest rocks that contain non-silicate minerals as primary components and, even if they represent only a fraction of all sedimentary rocks (about 20 – 25%), their study is fundamental to understand past environments, climate, and the evolution of life. This limestone is fine and uniform, found in thin beds that were once shallow stagnant hypersaline and anoxic lagoons. Due to high salt, low oxygen, and still water, few organisms ventured through this rock, leaving it to form near-perfect homogeneity. Oolitic Limestone. Oolitic limestone is composed of oolites. Limestone (calcium carbonate CaCO 3) 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 CaCO 3.Limestone forms when these minerals precipitate out of water containing dissolved calcium.
