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
Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix

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.
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.

All about Felsite and Conglomerate Properties
Know all about Felsite and Conglomerate properties here. All properties of rocks are important as they define the type of rock and its application. Felsite belongs to Igneous Rocks while Conglomerate belongs to Sedimentary Rocks.Texture of Felsite is Arborescent Patterned, Vitreous whereas that of Conglomerate is Clastic. Felsite appears Layered, Banded, Veined and Shiny and Conglomerate appears Shiny and Rounded. The luster of Felsite is vitreous while that of Conglomerate is dull. Felsite is available in black, blue, brown, green, orange, red, tan, yellow colors whereas Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow colors. The commercial uses of Felsite are mirror, jewelry and that of Conglomerate are cemetery markers, in aquifers, tombstones.
