The Bahamas Platform A NASA satellite image of the Bahamas Platform where active limestone formation occurs today. The main platform is over 100 miles wide, and a great thickness of calcium carbonate sediments have accumulated there. In this image the dark blue areas are deep ocean waters. The shallow Bahamas Platform appears as light blue. Enlarge image.

Limestone Vs Marble Hunker

Limestone Vs Marble Hunker

While granite gets all the attention in the kitchen, it39s not the only natural stone used in the home. Limestone and marble, which share many properties, each offer benefits to homeowners seeking out alternative finishes for walls, floors and other surfaces. Though both limestone and marble consist of calcium carbonate, they differ significantly in terms of appearance, composition and application.

While both limestone and marble are millions of years old, think of limestone as marble39s younger cousin. Limestone, a sedimentary rock, forms when shells, sand and fossils solidify over millions of years. When limestone experiences high heat and pressure beneath the earth, it may transform into marble, a metamorphic rock. As the rock is subject to natural heat and pressure, it recrystallizes, growing harder and denser over time. Mineral deposits add color and give marble its distinctive veinin

Despite their similar origins and composition, marble and limestone are easy to distinguish with the naked eye. Limestone typically comes in natural colors such as gray, tan or brown, and features impressions left by fossils and shells. Marble comes in a much wider variety of colors, from white to black, including pinks, tans, grays, reds, blues and greens. All of the fossils within the stone have long recrystallized, and are no longer visible, though the marble may feature veining and streaks o

In addition to their similar roots, marble and limestone share another similarity both are highly vulnerable to damage when exposed to acidic materials. For homeowners, this means that something as simple as a spilled glass of lemonade or drop of vinegar can leave permanent dull marks on the surface of the stone. This acid etching can only be removed by professionally resurfacing and rehoning the stone.

The price of marble and limestone can vary dramatically based on the color, source and treatment of the stone. While limestone generally costs less than other types of stone because it39s so widely available and easy to work with, according to Coldspring USA, highly polished limestone or rare colors can easily cost more than certain types of marble.

Limestone is more porous than marble, because there are small openings between the fossil fragments. Marble is usually light colored and is composed of crystals of calcite locked together like pieces of a jigsaw puzzle. Marble may contain colored streaks that are inclusions of non-calcite minerals.

An Explanation Of How Limestone Caves Are Formed At

Open limestone channels OLCs are constructed to direct AMD flows within a channel that has been lined with limestone. An OLC is very much like an ALD without a cap. An OLC is an oxygenated environment, so the Fe present in the AMD can armor, or coat, the limestone present in the channel. However, by incorporating the OLC into steep terrain or within watersheds that are subjected to periodic high flows during flooding events, the treatment properties of the armored limestone can be regenerated by

Brushing is done, as the name suggests, by brushing the stone with steel or hard nylon brushes. It leaves a lightly textured surface that tends to be more resilient to scratches and marks. It works particularly well on limestone and some sandstones and can also be applied effectively to tumbled marble. The example below shows a brushed Spanish Limestone Cenia Cream, and demonstrates how the brushing adds texture by gently removing the softer parts of the stone leaving a rippled surface.

A flamed finish is created by passing an oxy-acetylene torch over the surface of the stone and then following it immediately with a cold pressurised jet of water to fracture the top surface of the stone. On some types of stone, such as limestone and sandstone as in the photo below of the Italian Pietra Serena, it gives a non-slip surface which is ideal for terraces or public paved areas. This is a specialised technique and not all quarries have this equipment in their workshops.

Sandblasting is a technique that also gives a more slip-resistant surface suitable for outside areas or for wet areas. We have used this on shower trays and wet-rooms and also on patios, as in the image below - sandblasted Italian Carrara marble set on Buzon pedestals. It is created by spraying the surface with sand, ceramic beads or other abrasive components at a high pressure onto the surface of the stone.
