1 Definition
1.1 Definition
Granulite is fine to medium grained metamorphic rock with a granular of polygonal crystals.
Slate is a fine-grained, foliated, homogeneous metamorphic rock derived from an original shale-type sedimentary rock composed of clay or volcanic ash through low-grade regional metamorphism

5.1 Formation
Granulite is a fine-grained granular metamorphic rock in which the main component minerals are feldspars and quartz and forms at high temperature and pressure conditions.
Slate is a low grade metamorphic rock that is generally formed by metamorphosis of mudstone or shale, under relatively low pressure and temperature conditions.

Granulite vs Slate Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Granulite and Slate Reserves. Granulite is fine to medium grained metamorphic rock with a granular of polygonal crystals.. Slate is a fine-grained, foliated, homogeneous metamorphic rock derived from an original shale-type sedimentary rock composed of clay or volcanic ash through low-grade regional metamorphism. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Granulite vs Slate information and Granulite vs Slate characteristics in the upcoming sections.

Granulite vs Slate Characteristics

Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Granulite vs Slate characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Granulite and Properties of Slate. Learn more about Granulite vs Slate in the next section. The interior uses of Granulite include Bathrooms, Countertops, Decorative aggregates, Entryways, Flooring, Homes, Hotels, Interior decoration, Kitchens and Stair treads whereas the interior uses of Slate include Bathrooms, Decorative aggregates, Entryways, Floor tiles, Flooring, Homes, Hotels, Interior decoration, Kitchens and Stair treads. Due to some exceptional properties of Granulite and Slate, they have various applications in construction industry. The uses of Granulite in construction industry include As dimension stone, Building houses or walls and that of Slate include As dimension stone.

More about Granulite and Slate

Here you can know more about Granulite and Slate. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granulite and Slate consists of mineral content and compound content. The mineral content of Granulite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Quartz and mineral content of Slate includes Apatite, Biotite, Chlorite, Feldspar, Graphite, Hematite, Kaolinite, Magnetite, Pyrite, Tourmaline, Zircon. You can also check out the list of all Metamorphic Rocks. When we have to compare Granulite vs Slate, the texture, color and appearance plays an important role in determining the type of rock. Granulite is available in black, brown colors whereas, Slate is available in black, brown, buff, green, light to dark grey, purple, red, shades of blue colors. Appearance of Granulite is Veined or Pebbled and that of Slate is Dull. Properties of rock is another aspect for Granulite vs Slate. The hardness of Granulite is 6-7 and that of Slate is 3-4. The types of Granulite are Not Available whereas types of Slate are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Granulite is white while that of Slate is light to dark brown. The specific heat capacity of Granulite is 0.14 kJ/Kg K and that of Slate is 0.76 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Granulite is heat resistant, wear resistant whereas Slate is heat resistant, impact resistant, pressure resistant, wear resistant.
