How is marble formed

Marble and granite are best for health and because they are naturally available and also because of non porous nature. Tiles, on the other hand, fare better than marble as it can be recycled, non-toxic and are manufactured using safe processes.

Marble is more expensive than tiles. This is because tiles are man-made while marble is a natural stone which has to be mined and extracted using costly procedures. Granite, like any other stone, may contain veins of naturally occurring radioactive elements like uranium, thorium, and their radioactive decay products. If present, uranium, thorium or radium will decay into radon, a colorless, odorless, radioactive gas that may cause lung cancer.

Hardness and longevity: Granite is comparatively harder and stronger than marble. It is mostly known as the most durable natural stone and compared to marble. Marble, on the other hand, has a grayish or cream color with veins running through it.

The veins in marble are usually due to impurities like iron oxide. Begin typing your search term above and press enter to search. Press ESC to cancel. Skip to content Home How is marble formed in nature? Ben Davis May 27, How is marble formed in nature? How is marble formed step by step?

The characteristic swirls and veins of many colored marble varieties are usually due to various mineral impurities such as clay, slt, sand, iron oxides, or chert which were originally present as grains or layers in the limestone. Green coloration is often due to serpentine resulting from originally high magnesium limestone or dolostone with silica impurities.

These various impurities have been mobilized and recrystallized by the intense pressure and heat of the metamorphism. Marble does not split easily into sheets of equal size and must be mined carefully. The rock may shatter if explosives are used. Blocks of marble are mined with channeling machines, which cut grooves and holes in the rock. Miners outline a block of marble with rows of grooves and holes. They then drive wedges into the openings and separate the block from the surrounding rock.

The blocks are cut with saws to the desired shape and size. Marble has long been highly valued for its beauty, strength, and resistance to fire and erosion. The ancient Greeks used marble in many buildings and statues. The Italian artist Michelangelo used marble from Carrara, Italy, in a number of sculptures.

Extremely pure calcite marble is used for most statues. This kind of marble is translucent--that is, light penetrates a short distance below the surface of the marble before it is reflected.

Large blocks of colored marble are used for columns, floors, and other parts of buildings. Smaller pieces of such marble are crushed or finely ground and used as abrasives in soaps and other products. Crushed or ground marble is also used in paving roads and in manufacturing roofing materials and soil treatment products.

Marble dust can be combined with cement or synthetic resins to make reconstituted or cultured marble. While a few marbles are indeed made of marble, the stone is too soft to be an ideal material for the modern game. The name of the toy reflects the appearance of the balls, not their composition.
