2022year9month27day · Marble 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

Limestone vs Dolomite: What Are They, And What's The
Limestone is an occurring type of sedimentary carbonate rock found on Earth’s surface. It is formed when crystals of calcium carbonate precipitate out of water containing dissolved calcium. Limestone is composed of minerals such as calcite and aragonite. Limestone consists of 80 percent calcite and Dolomite with more than 50% calcium carbonate.

2002year11month11day · Marble. Marbles are limestones or dolostones that have been metamorphosed. Since metamorphism recrystallizes the individual calcite or dolomite crystals in the parent rock, slightly metamophosed limestones have textures that look slightly blurred compared to a fresh limestone. Such marbles are commonly used as floor tiles

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.

Is it Calcite or Dolomite? - Magzter
Calcite responds vigorously to acid, while dolomite responds less vigorously. Calcite is 3 on the Mohs Scale of Hardness, but dolomite is Mohs 4-4.5. One other difference you may see is the smoothness of the crystal faces on your specimen. Dolomite crystals, because of an unusual internal structure, may have slightly curved crystal faces, while ...
