5.1 Formation

Felsite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

Norite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

Felsite vs Norite 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 Felsite and Norite Reserves. Felsite is a very fine grained volcanic rock that may or may not contain larger crystals and light colored rock that typically requires petrographic examination or chemical analysis for more precise definition. Norite is a mafic intrusive igneous rock composed largely of the calcium-rich plagioclase labradorite, orthopyroxene, and olivine. 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 Felsite vs Norite information and Felsite vs Norite characteristics in the upcoming sections.

Felsite vs Norite 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. Felsite vs Norite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Felsite and Properties of Norite. Learn more about Felsite vs Norite in the next section. The interior uses of Felsite include Decorative aggregates, Flooring and Interior decoration whereas the interior uses of Norite include Decorative aggregates, Entryways and Interior decoration. Due to some exceptional properties of Felsite and Norite, they have various applications in construction industry. The uses of Felsite in construction industry include Arrowheads, Cutting tool, Knives, Scrapers, Spear points and that of Norite include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate.

More about Felsite and Norite

Here you can know more about Felsite and Norite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Felsite and Norite consists of mineral content and compound content. The mineral content of Felsite includes Feldspar, Iron Oxides and mineral content of Norite includes Augite, Olivine, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Felsite vs Norite, the texture, color and appearance plays an important role in determining the type of rock. Felsite is available in black, blue, brown, green, orange, red, tan, yellow colors whereas, Norite is available in dark grey to black colors. Appearance of Felsite is Layered, Banded, Veined and Shiny and that of Norite is Veined and Shiny. Properties of rock is another aspect for Felsite vs Norite. The hardness of Felsite is 5-5.5 and that of Norite is 7. The types of Felsite are Not Available whereas types of Norite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Felsite is white while that of Norite is black. The specific heat capacity of Felsite is 0.92 kJ/Kg K and that of Norite is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Felsite is heat resistant, impact resistant whereas Norite is impact resistant, pressure resistant, wear resistant.
