Marble Rocks Compare Nature

The streak of marble is white.

Marble rocks compare nature.

The strength of marble is 115 00 n mm 2. 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. The streak of a rock is the color of powder produced when it is dragged across an unweathered surface. 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 specific heat capacity of granite is 0 79 kj kg k and that of marble is 0 88 kj kg k. Marble is usually a light colored rock. 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. Luster of marble is dull to pearly to subvitreous and its fracture is not available.

We all come across rocks in our day to day life be it a stone pebble sand or just mud. When it is formed from a limestone with very few impurities it will be white in color. Physical properties of marble include color streak hardness structure cleavage fracture luster specific gravity etc. Streak of marble is white while its cleavage is perfect.

Marble that contains impurities such as clay minerals iron oxides or bituminous material can be bluish gray pink yellow or black in color. Marble is opaque in nature. The internal carbonate crystal structure of limestone and marble are different to each other.
