Definition
Enderbite rock is an igneous rock which belongs to the Charnockite rock series
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

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.
