Definition

Charnockite is a variety of granite containing minerals like orthopyroxene, quartz, and feldspar

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

Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.

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.
