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
Blue Granite is an igneous rock and a variety of Larvikite, notable for the presence of thumbnail-sized blue crystals of feldspar

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.
Blue Granite is an igneous rock which is a variety of Larvikite and is known mainly for the presence of thumbnail-sized crystals of feldspar.

More about Felsite and Blue Granite
Here you can know more about Felsite and Blue Granite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Felsite and Blue Granite consists of mineral content and compound content. The mineral content of Felsite includes Feldspar, Iron Oxides and mineral content of Blue Granite includes Albite, Amphibole, Apatite, Biotite, Feldspar, Hornblade, Ilmenite, Magnetite, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz, Sulfides, Titanite, Zircon. You can also check out the list of all Igneous Rocks. When we have to compare Felsite vs Blue Granite, 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, Blue Granite is available in black, brown, light to dark grey, white colors. Appearance of Felsite is Layered, Banded, Veined and Shiny and that of Blue Granite is Shiny. Properties of rock is another aspect for Felsite vs Blue Granite. The hardness of Felsite is 5-5.5 and that of Blue Granite is 6-7. The types of Felsite are Not Available whereas types of Blue Granite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Felsite and Blue Granite is white. The specific heat capacity of Felsite is 0.92 kJ/Kg K and that of Blue Granite is 0.79 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 Blue Granite is heat resistant, impact resistant, pressure resistant.
