Definition
Adamellite is a coarse-grained porphyritic igneous rock, a variety of Monzogranite and dominated by phenocrysts of orthoclase in a granular groundmass of perthite, plagioclase and quartz
Charnockite is a variety of granite containing minerals like orthopyroxene, quartz, and feldspar

Formation
Adamellite is a type of Igneous rock which is formed through the cooling and solidification of lava or magma and is a variety of Monzogranite.
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.
