Felsite vs Sandstone


Definition

Definition
Sandstone is defined as a rock which is composed of sand-sized grains of various minerals mostly of uniform size and often are smooth and rounded  
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

Formation

Formation
Sandstone is a sedimentary rock which forms from cemented sand-sized clasts. It forms when sand layers are buried under sediments of sand.   
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.

Sandstone 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 Sandstone and Felsite Reserves. Sandstone is defined as a rock which is composed of sand-sized grains of various minerals mostly of uniform size and often are smooth and rounded. 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 Sandstone vs Felsite information and Sandstone vs Felsite characteristics in the upcoming sections.

Sandstone 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. Sandstone vs Felsite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Sandstone and Properties of Felsite. Learn more about Sandstone vs Felsite in the next section. The interior uses of Sandstone include Countertops, Decorative aggregates and Interior decoration whereas the interior uses of Felsite include Decorative aggregates, Flooring and Interior decoration. Due to some exceptional properties of Sandstone and Felsite, they have various applications in construction industry. The uses of Sandstone in construction industry include Cement manufacture, Construction aggregate, For road aggregate, Production of glass and ceramics, Raw material for the manufacture of mortar and that of Felsite include Arrowheads, Cutting tool, Knives, Scrapers, Spear points.

More about Sandstone and Felsite

Here you can know more about Sandstone and Felsite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Sandstone and Felsite consists of mineral content and compound content. The mineral content of Sandstone includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz and mineral content of Felsite includes Feldspar, Iron Oxides. You can also check out the list of all Sedimentary Rocks. When we have to compare Sandstone vs Felsite, the texture, color and appearance plays an important role in determining the type of rock. Sandstone is available in beige, black, brown, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors whereas, Felsite is available in black, blue, brown, green, orange, red, tan, yellow colors. Appearance of Sandstone is Rough and that of Felsite is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Sandstone vs Felsite. The hardness of Sandstone is 6-7 and that of Felsite is 5-5.5. The types of Sandstone are Grey Sandstones, Crystallized Sandstones, Hard Sandstones , Carbonate Cemented Sandstones and Ganister whereas types of Felsite are Igneous rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Sandstone and Felsite is white. The specific heat capacity of Sandstone is 0.92 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.Sandstone is heat resistant, impact resistant, pressure resistant whereas Felsite is heat resistant, impact resistant.
