Ambaji Marble Latest News

Recently, the Ambaji Marble has been awarded the Geographical Indication (GI) tag for its high-quality white stone.

About Ambaji Marble

• It is named after the town of Ambaji in the state of Gujarat, where it is predominantly quarried. 
• It is a type of marble known for its milky white colour, durability and natural beauty.

Features of Ambaji Marble

• Appearance: It is characterized by its pristine white color, which often features subtle gray or beige veining.
  • The veins can vary in intensity and they occur naturally due to the presence of minerals and impurities during the marble formation process.
• Durability: It has very long-lasting shine and durability. 
• Applications of Ambaji Marble: It has been used in the construction of Ambaji temple and many other religious places, memorials and grand buildings.

Key Facts about Marble

• It is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism.
• Composition: It is composed primarily of the mineral calcite (CaCO3) and usually contains other minerals, such as clay minerals, micas, quartz, pyrite, iron oxides, and graphite.

Formation of Marble

• Under the conditions of metamorphism, the calcite in the limestone recrystallizes to form a rock that is a mass of interlocking calcite crystals.
• A related rock, dolomitic marble, is produced when dolostone is subjected to heat and pressure.
• The transformation of limestone into marble usually occurs at convergent plate boundaries, where large areas of Earth’s crustare exposed to the heat and pressure of regional metamorphism.
• Some marble also forms by contact metamorphism when a hot magma body heats adjacent limestone or dolostone.
