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.

We all come across rocks in our day to day life be it a stone pebble sand or just mud. Marble is available in black blue brown grey pink white colors. Depending on the properties like hardness toughness specific heat capacity porosity etc rocks are resistant to heat wear impact etc granite is heat resistant wear resistant whereas marble is heat resistant. Physical properties of marble include color streak hardness structure cleavage fracture luster specific gravity etc.

The specific heat capacity of granite is 0 79 kj kg k and that of marble is 0 88 kj kg k. 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. The strength of marble is 115 00 n mm 2. Marble is opaque in nature.

Luster of marble is dull to pearly to subvitreous and its fracture is not available. The streak of a rock is the color of powder produced when it is dragged across an unweathered surface. 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. Marble is usually a light colored rock.

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. When it is formed from a limestone with very few impurities it will be white in color. The internal carbonate crystal structure of limestone and marble are different to each other.
