Diorite Formation Diorite is intrusive igneous rock So when the partial melting of an oceanic plate takes place the resulting basaltic magma rises and intrudes on the rocky continental plate If granitic magma or rocks are present there the mixing of basaltic and granitic magmas are taking place under the continental crust/plate

Pegmatites form from waters that separate from a magma in the late stages of crystallization this activity often occurs in small pockets along the margins of a batholith Pegmatite can also form in fractures that develop on the margins of the batholith This is how pegmatite dikes are formed

Diorite is formed as a result of the partial melting of marine plates in the production of basaltic magma As this magma rises Diorite reaches the granite rock of the continental plate Basaltic magma in its composition melts the granite bed Diorite produces granitic magma

Diorite is usually associated with subduction zones It may be a product of partial melting of mafic protolith but it may also form as a result of mixing between mafic melt and felsic country rocks It occurs in both continental and oceanic crust and is not a rare rock type but it is significantly less common than granite and other granitoids

Andesite is a volcanic rock It is fine grained because it forms by the rapid cooling of magmas usually when it erupts onto the Earth s surface and forms lava flows Andesite forms from magma that contains less quartz silica than rhyolite but more than basalt It is therefore often referred to as intermediate in composition
