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 ...
