Limestone is a sedimentary rock; it is composed mostly of the mineral calcite. It is nearly pure calcite; the calcite is derived mostly from the remains of organisms such as clams and corals that accumulate on the bottom of the sea as debris. This shelly debris can then form beds of limestone. Although some limestone’s can be nearly pure calcite, there is often a large amount or sand or silt that is included in the shelly debris. Limestone is almost always marine (ocean water) in origin and is usually associated with other near shore rocks types. Coal and Limestone’s are important rocks; they can be used for building materials but are not quite as strong as sandstone and are easily weathered by acidic conditions. Limestones are the primary source of lime for cements. Cement is considered one of the most important construction materials ever invented by man. Limestone can be crushed and used as road ballast. Significant quantities of limestone are quarried around the world for these purposes. Limestone forms the metamorphic rock, marble. During the metamorphic process, the crystals of fine grained calcite in the limestone become merged and molded into other large crystals forming the interlocking course grained texture of the marble. All limestone does under go some kind of alteration after initial solidification. These alterations can include dolomitization, recrystalization, compaction or cementation. All of these things are considered part of the digenetic process. Digenesis is anything that happens to a sedimentary rock after original deposition. At some point digenesis and metamorphism meet and the stone is no longer a limestone, but a marble. The boundaries between the two are well studied and usually not difficult to distinguish as significant changes occur to the calcite crystals during metamorphism. Gappsi limestones are imported from all over the world. Limestone can be finished in many textures and shapes. They are non slip non porous high compressive strength, resistant to wear and have excellent stain removability. There are applications from flooring and wall cladding to paving and building facades. Limestone can be fished in honed, polished, tumbled, sand blasted, antiqued, flamed, natural and hand cut.
