Marble Rocks Compare Nature

Luster of marble is dull to pearly to subvitreous and its fracture is not available.

Marble rocks compare nature. The streak of a rock is the color of powder produced when it is dragged across an unweathered surface. 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 streak of marble is white. The strength of marble is 115 00 n mm 2.

The internal carbonate crystal structure of limestone and marble are different to each other. Streak of marble is white while its cleavage is perfect. 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. The specific heat capacity of granite is 0 79 kj kg k and that of marble is 0 88 kj kg k.

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. We all come across rocks in our day to day life be it a stone pebble sand or just mud. Sign in google accounts.

Marble is available in black blue brown grey pink white colors. Physical properties of marble include color streak hardness structure cleavage fracture luster specific gravity etc. When it is formed from a limestone with very few impurities it will be white in color.
