Basanite  vs Felsite

1 Definition
1.1 Definition
Basanite is a black basaltic rock which mainly contains plagioclase, augite, olivine and nepheline and is formerly used as a touchstone
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

Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.
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.

Basanite  vs Felsite 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 Basanite  and Felsite Reserves. Basanite is a black basaltic rock which mainly contains plagioclase, augite, olivine and nepheline and is formerly used as a touchstone. 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. 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 Basanite  vs Felsite information and Basanite  vs Felsite characteristics in the upcoming sections.

Basanite  vs Felsite 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. Basanite  vs Felsite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Basanite  and Properties of Felsite. Learn more about Basanite  vs Felsite in the next section. The interior uses of Basanite  include Decorative aggregates and Homes whereas the interior uses of Felsite include Decorative aggregates, Flooring and Interior decoration. Due to some exceptional properties of Basanite  and Felsite, they have various applications in construction industry. The uses of Basanite  in construction industry include Arrowheads, Construction aggregate, Cutting tool, Spear points and that of Felsite include Arrowheads, Cutting tool, Knives, Scrapers, Spear points.

More about Basanite  and Felsite

Here you can know more about Basanite  and Felsite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Basanite  and Felsite consists of mineral content and compound content. The mineral content of Basanite  includes Augite, Feldspar, Ilmenite, Olivine, Plagioclase and mineral content of Felsite includes Feldspar, Iron Oxides. You can also check out the list of all Igneous Rocks. When we have to compare Basanite  vs Felsite, the texture, color and appearance plays an important role in determining the type of rock. Basanite  is available in black, brown, green, grey, red, white colors whereas, Felsite is available in black, blue, brown, green, orange, red, tan, yellow colors. Appearance of Basanite  is Glassy or Pearly and that of Felsite is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Basanite  vs Felsite. The hardness of Basanite  is 7 and that of Felsite is 5-5.5. The types of Basanite  are Nepheline-Basanite, Analcite-Basanite and Leucite-Basanite whereas types of Felsite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Basanite  and Felsite is white. The specific heat capacity of Basanite  is 0.74 kJ/Kg K and that of Felsite is 0.92 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Basanite  is heat resistant, impact resistant, pressure resistant, wear resistant whereas Felsite is heat resistant, impact resistant.
