Definition

Diorite is a grey to dark-grey intermediate intrusive igneous rock composed principally of plagioclase feldspar,biotite, hornblende, and pyroxene

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

Formation

Diorite is a coarse-grained intrusive igneous rock which contains large interlocking and randomly oriented crystals and forms when molten lava does not reach the Earth’s surface and cools down in the Earth’s crust.

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.
