How does acid precipitation affect marble and limestone ...

When sulfurous, sulfuric, and nitric acids in polluted air and rain react with the calcite in marble and limestone, the calcite dissolves. In exposed areas of buildings and statues, we see roughened surfaces, removal of material, and loss of carved details. Stone surface material may be lost all over or only in spots that are more reactive.

What is the difference between chalk, limestone and marble ...

 · Limestone is formed in a shallower marine environment from the bodies of corals and shells, as well as the shells of microscopic sea life. Since it contains large lumps, it does not form such a fine white powder as chalk. Marble is metamorphosed limestone, ie subjected to heat and pressure, the crystals grow and interlock, forming a stronger ...

Limestone vs. Marble: Which Is Better For Your Bathroom?

 · Both limestone and marble tend to react with acidic substances by forming a gray or black crust of gypsum crystals. Thus, we can safely assume that acidic substances will stain both of these stones. In terms of pure hardness, we can consult the Mohs scale again to check the relative hardness of these substances.

Calcium carbonate | Podcast | Chemistry World

Chalk and limestone are fairly similar materials, chalk being less compacted and so softer. Marble takes longer to form, starting with a raw material of chalk or limestone that then gets transformed by heat and pressure, recrystallising to produce a significantly harder interlocking structure of crystals.

Calcium Carbonate Facts

Calcium carbonate (CaCO 3) is a chemical compound of calcium. It is the main component of the shells of marine organisms such as oysters, snails shells, pearls, coral and eggshell. Calcium carbonate occurs as minerals aragonite and calcite. These carbonate minerals form the rock types of limestone, chalk, marble, travertine, tufa and coquina.

What is Limestone? (with pictures)

As an example of the diversity of limestone, both chalk and marble are forms of limestone, even though these two rock varieties look and feel very different. In the case of chalk, the rock is soft, typically white, and crumbly, while marble is hard, with crystalline grains and an array of colors which commonly includes large seams of color.

Exploring Varieties of Limestone

Limestone comes in a lot of different colors, which are determined by the non-limestone materials infused into a given rock. In order to achieve black limestone, the specimen must have high levels of organic material dispersed throughout. Chalk Limestone. Chalk limestone is soft, fine, and tends to range in color from white to light grey.
