1.1 Definition

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

Troctolite is a mafic intrusive rock type. It consists essentially of major but variable amounts of olivine and calcic plagioclase along with minor pyroxene. It is an olivine-rich anorthosite, or a pyroxene-depleted relative of gabbro

4.2 Formation

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

Troctolite 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.
