Marble that contains impurities such as clay minerals, iron oxides, or bituminous material can be bluish, gray, pink, yellow, or black in color. When it is formed from a limestone with very few impurities, it will be white in color. The best thing about marble is that it is available in different colors due to the presence of various minerals like sand, silt and clay. It is known for its durability and its toughness to combat scratch and heat. Marble has long been highly valued for its beauty, strength, and resistance to fire and erosion. The chemical composition of marble is composed of the following major constituents: Lime (CaO), Silica (SiO2), Alumina (Al2O3), oxides (NaO and MgO), and (MgCO3 and others). Marble is composed primarily of calcite, dolomite, or perhaps serpentine. This will result in the formation of an igneous rock, not a metamorphic rock. If there is too much heat or pressure, the rock will melt and become magma. In order to create metamorphic rock, it is vital that the existing rock remain solid and not melt. These conditions are most commonly found either deep in the crust of Earth or at the boundaries of plate where tectonic plates collide. The existing rock must be exposed to high heat, high pressure or a hot fluid rich in minerals. The conditions necessary for the formation of a metamorphic rock are very precise and make it harder than sedimentary marble. Metamorphic rocks are rocks that have been changed from their original form by immense heat or pressure. They do not melt, but the minerals they contain are changed chemically, forming metamorphic rocks. As a result, the rocks are heated and put under great pressure. Further, earth movements can cause sedimentary rocks to be deeply buried or squeezed. This sediment then further gets compressed over time and becomes solid layers of rocks. They are formed when minerals and other sediment sit in oceans and lakes for millions of years. Sedimentary rocks are formed through the solidification of sediments. Sedimentary rocks were originally sediments, which were compacted under high pressure. Erosion, weathering, dissolution, precipitation, and lithification are the most important geological processes leading to the creation of sedimentary rocks. Sedimentary rocks are the one that are formed on or near the surface of the Earth. Clay, sand, or chert mineral impurities may often produce distinctive veins and swirls within the marble, producing spectacular patterns and discolorations that homeowners and decorators are highly sought after. There may also be a variety of other changes, depending on what’s present during the process, including water or other mineral components. At far higher temperatures and with rarer calcium minerals like larnite, other formations are created within the marble. Depending upon the certain temperature, silica impurities react with the carbonate to produce crystals of quartz, or forsterite.

And when there are impurities present in the limestone during this transformation, amazing effects and changes take place in the mineral composition. Large masses of calcite are created when the original carbonate and fossilized materials are recrystallized. The conditions it is put under will cause the limestone to change in its very makeup, as well as texture and appearance, in a process known as crystallization. Marble is formed from limestone by heat and pressure in the earth’s crust. With the progression of the process, the crystals become larger and easily recognizable. During the process of metamorphism, the calcite recrystallizes that further changes the texture of marble.

A large part of earth’s crust is exposed to metamorphism. Most marbles form at convergent plate boundaries. Under heat and pressure caused by magma or the tectonic plates, this limestone begins to recrystallize, changing the texture of the rock and causing the calcite crystals to grow and interlock. Sedimentary rock is formed at or near the Earth’s surface by the accumulation and lithification of sediment (detrital rock). Marble begins life as sedimentary rock known as limestone, which is a soft stone made primarily of calcite. We can customize the sizes from small tiles into large slabs.Įxplore our Indonesia Marble Tiles product from here.Marble is a rock composed of recrystallized carbonate minerals, with the maximum concentration of calcite or dolomite. Our Indonesia Marble Tiles normally has used for interior and exterior flooring tiles. Our Indonesia Marble tiles divided into three types beige marble, grey marble, and cream marble.
