Marble Rocks Compare Nature

Marble that contains impurities such as clay minerals iron oxides or bituminous material can be bluish gray pink yellow or black in color.

Marble rocks compare nature.

Marble is available in black blue brown grey pink white colors. Rocks are also classified on the basis of their hardness which ranges from 1 to 10 on moh s hardness scale as types of hard rocks types of soft rocks and rocks with medium hardness. Marble is a non foliated metamorphic rock which is composed of recrystallized carbonate which is formed when limestone is exposed to high temperatures and pressures over a long time. Limestone is a type of sedimentary rock formed by the deposition of natural carbonate material whereas marble is a type of metamorphic rock formed by metamorphism of limestone.

The internal carbonate crystal structure of limestone and marble are different to each other. Physical properties of marble include color streak hardness structure cleavage fracture luster specific gravity etc. The streak of a rock is the color of powder produced when it is dragged across an unweathered surface. Streak of marble is white while its cleavage is perfect.

Luster of marble is dull to pearly to subvitreous and its fracture is not available. The strength of marble is 115 00 n mm 2. Marble is usually a light colored rock. When it is formed from a limestone with very few impurities it will be white in color.
