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
Limestone is a sedimentary rock composed mostly of calcite and aragonite, which are different crystal forms of calcium carbonate

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.
Limestone is a sedimentary rock which is mainly made up of calcium carbonate.

All about Felsite and Limestone Properties
Know all about Felsite and Limestone properties here. All properties of rocks are important as they define the type of rock and its application. Felsite belongs to Igneous Rocks while Limestone belongs to Sedimentary Rocks.Texture of Felsite is Arborescent Patterned, Vitreous whereas that of Limestone is Clastic or Non-Clastic. Felsite appears Layered, Banded, Veined and Shiny and Limestone appears Rough and Banded. The luster of Felsite is vitreous while that of Limestone is dull to pearly. Felsite is available in black, blue, brown, green, orange, red, tan, yellow colors whereas Limestone is available in beige, black, blue, brown, cream, gold, green, grey, light green, light grey, linen, pink, red, rust, silver, white, yellow colors. The commercial uses of Felsite are mirror, jewelry and that of Limestone are animal feed filler, as a feed additive for livestock, paper industry, raw material for manufacture of quicklime, slaked lime, soil conditioner, used in aquariums, whiting material in toothpaste, paint and paper.
