Sedimentary rocks are a type of rocks that form via accumulation or deposition of sediment ... Limestone is made up of calcium carbonate (fizzes with acid). This may be shell fragments, mud, or small, round ooliths that form in tropical lagoons. Chalk is a soft white limestone made from the microscopic skeletons of marine plankton.Effects of Rock Salt on Limestone. Although all rocks are solid, they actually have various degrees of hardness and porousness. If a rock is too soft, it is going to be more easily affected by external factors, like salt, which can damage the integrity of the rock. Whenever limestone is used in building, care must be taken to protect it from ...fossils (e.g. fossiliferous limestone) ooliths; pellets; In contrast, the chemically-precipitated limestones consist solely of crystalline carbonates (e.g. microcrystalline limestone). The clastic limestones can be further subdivided according to their grainsize, much like other clastic sedimentary rocks. Other chemical sedimentary rocks If these layers are buried deeply enough to be lithified into sedimentary rock, they will become sandstone, shale and limestone. This is a transgressive sedimentary sequence, from the bottom up, sandstone-shale-limestone. A regressive sedimentary sequence represents the lowering of sea level and the retreat of the sea from the low-lying land.There is considerable confusion as to the difference between slate and flagstone. In many discussions on this topic, terms such as shale, slate, limestone, bluestone, paver, flagstone and landscaping stone are bandied about.
