Examples of phaneritic igneous rocks are gabbro, diorite and granite. The most common rock types in plutons are granite, granodiorite, tonalite, monzonite, and quartz diorite. Andesine occurs in intermediate igneous rocks such as diorite, syenite and andesite. There are intrusions of igneous rocks, such as gabbro, diabase, and diorite. The host rocks tend to be quartz diorite and granodiorite. The chemical composition of diorite is intermediate, between that of mafic gabbro and felsic granite. Magnesian orthopyroxene occurs in plutonic rocks such as gabbro (norite) and diorite. The older one consists of granodiorite and adamellite with inclusions of tonalite, diorite, and gabbro. Andesite can be considered as the extrusive equivalent of plutonic diorite. Gold was also mined from lode veins within andesite and diorite. It comprises various rock types including gabbro, ferro diorite, anorthosite and granophyre. The Swaziland Middleveld is dominated by soils and saprolite, formed out of diorite and granodiorite. Amphibolite, diorite, gabbro and quartz diorite are common in the south. There are also incidences of gabbro and diorite, less commonly eclogite. The found materials include Basalt, Granite, Diorite, Marble, and Quartzite.
