Felsite vs Basanite 

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

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

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

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

More about Felsite and Basanite 

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