Marble

What is Marble?

Marble is a metamorphic rock composed of recrystallized carbonate minerals, most commonly calcite or dolomite. This stone forms when limestone is subjected to the heat and pressure of metamorphism. Usually, it contains other minerals, such as clay minerals, micas, quartz, pyrite, iron oxides, and graphite. Meanwhile, insufficient amounts can affect the texture and color of the marble.

Name Origin

The word “marble” derives from the Ancient Greek mármaros, “crystalline rock, and shining stone”

How Does Marble Form?

Firstly, the metamorphism of the limestone and 1200-1,500 bar and between 125-180 degrees Celsius remote exposure to high pressure and temperature of the marble there.

In addition, The metamorphism of the limestone is required by marble, extra iron, and graphite (in smaller quantities). As the metamorphism progresses, the crystals grow and the interlocking calcite Changing colors are the result of the duration of the impurity function and metamorphosis.

Physical Properties

  • Derived: Limestone, dolomite
  • Grain size – medium grained; can see interlocking calcite crystals with the naked eye.
  • Hardness – hard, although component mineral is soft (calcite is 3 on Moh’s scale of hardness
  • Structure: Massive
  • Group: Metamorphic Rocks
  • Texture: Granoblastic, granular.
  • Formation: Regional or contact metamorphic
  • Acid Reaction: Being composed of calcium carbonate, marble will react in contact with many acids, neutralizing the acid. It is one of the most effective acid neutralization materials. It is often crushed and used for acid neutralization in streams, lakes, and soils.
  • Hardness: Being composed of calcite, it has a hardness of three on the Mohs hardness scale. As a result, it is easy to carve, and that makes it useful for producing sculptures and ornamental objects. The translucence of marble makes it especially attractive for many types of sculptures.
  • Ability to Accept a Polish: further, being sanded with progressively finer abrasives, it can be polished to a high luster. This allows attractive pieces of marble to be cut, polished, and used as floor tiles, architectural panels, facing stone, windowsills, stair treads, columns, and many other pieces of decorative stone.
  • Major minerals: Calcite
  • Accessory minerals: Diopside, tremolite, actinolite, dolomite

Where Is It Located?

Marble deposits can be found in various countries around the globe. European countries such as Italy, Ireland, Spain, Greece, Russia, Romania, Sweden, and Germany. in addition to others in Asia, are among the globe’s leading producers of this valuable rock. The United States of America is also a high-level producer, with states such as Alabama and Texas having especially large deposits to be found within their borders. However, Italy, China, India, and Spain dominate global Marble production. More information on Wikipedia.
