Definition
Jadeitite is a metamorphic rock usually found in blueschist grade metamorphic terrains
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

Archaeological Significance
Formation
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Jadeitite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.
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.

Jadeitite 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. Jadeitite vs Felsite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Jadeitite and Properties of Felsite. Learn more about Jadeitite vs Felsite in the next section. The interior uses of Jadeitite include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Felsite include Decorative aggregates, Flooring and Interior decoration. Due to some exceptional properties of Jadeitite and Felsite, they have various applications in construction industry. The uses of Jadeitite in construction industry include As dimension stone, Cutting tool, Knives and that of Felsite include Arrowheads, Cutting tool, Knives, Scrapers, Spear points.
More about Jadeitite and Felsite
Here you can know more about Jadeitite and Felsite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Jadeitite and Felsite consists of mineral content and compound content. The mineral content of Jadeitite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides and mineral content of Felsite includes Feldspar, Iron Oxides. You can also check out the list of all Metamorphic Rocks. When we have to compare Jadeitite vs Felsite, the texture, color and appearance plays an important role in determining the type of rock. Jadeitite is available in black, brown, green, grey, white colors whereas, Felsite is available in black, blue, brown, green, orange, red, tan, yellow colors. Appearance of Jadeitite is Rough and Dull and that of Felsite is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Jadeitite vs Felsite. The hardness of Jadeitite is 3-5 and that of Felsite is 5-5.5. The types of Jadeitite are Metamorphic rock 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 Jadeitite and Felsite is white, greenish white or grey. The specific heat capacity of Jadeitite is 0.95 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.Jadeitite is heat resistant, water resistant whereas Felsite is heat resistant, impact resistant.
