Definition
Diamictite is a sedimentary rock that consists of non-sorted to poorly sorted terrigenous sediment containing particles that range in size from clay to boulders, suspended in a matrix of mudstone or sandstone
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
Diamictite is unevenly sorted terrigenous, non-calcareous sedimentary rock which forms due to weathering of mudstone and sandstone.
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.

All about Diamictite and Felsite Properties
Know all about Diamictite and Felsite properties here. All properties of rocks are important as they define the type of rock and its application. Diamictite belongs to Sedimentary Rocks while Felsite belongs to Igneous Rocks.Texture of Diamictite is Clastic whereas that of Felsite is Arborescent Patterned, Vitreous. Diamictite appears Banded and Felsite appears Layered, Banded, Veined and Shiny. The luster of Diamictite is grainy, pearly and vitreous while that of Felsite is vitreous. Diamictite is available in brown, buff colors whereas Felsite is available in black, blue, brown, green, orange, red, tan, yellow colors. The commercial uses of Diamictite are commemorative tablets, creating artwork, production of lime and that of Felsite are mirror, jewelry.
