How Is Marble Formed? - Marble and Granite
Marble is a metamorphic rock formed when limestone is exposed to high temperatures and pressures. Marble forms under such conditions because the calcite forming the limestone recrystallises forming a denser rock consisting of roughly equigranular calcite crystals. The variety of colours exhibited by marble are a consequence of minor amounts of impurities being incorporated with the calcite during

Marble is a rock made of calcium carbonate which has been exposed to a natural recrystallization process. Marble is being created by the transformation of other stones through the action of high temperatures and intense pressures. As a result of this process new minerals, textures, and structures give rise to a large number of different types of marble, as we will see in the examples below.
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. Limestone is made of fossil fragments, held together with calcite; the shell near the center is about 1 cm across.
