Other articles where Tholeiitic basalt is discussed: basalt: Tholeiitic basaltic lavas are characterized by calcic plagioclase with augite pigeonite or hypersthene and olivine (rarely) as the dominant mafic minerals basalts without olivine are also well represented Tholeiitic basalts which contain 45 to 63 percent silica are rich in iron and include the tholeiites

Basalts are often porphyritic and can contain mantle xenoliths As basic rocks they contain between 45-50% silica abundant Fe Mg and Ca and little Na and K The coarse and medium-grained equivalents of basalt are gabbro and dolerite respectively Basalt is distinguished from pyroxene andesite by its more calcic plagioclase

English: Diagram showing the classification of basalt according to degree of silica saturation into three types: alkali basalt (left of the purple plane in the tetrahedron) olivine tholeiite (plots between the two coloured planes in the tetrahedron) and quartz tholeiite (plots right of the green plane in the tetrahedron)

Volcanic rock (or lava) that characteristically is dark in color (gray to black) contains 45 to 53 percent silica and is rich in iron and magnesium Basaltic lavas are more fluid than andesites or dacites which contain more silica Basalt is the most common rock type in the Earth's crust (the outer 10 to 50 km) In fact most of the ocean floor is made of basalt

Silica saturated basalts are called Olivine Tholeiites Normative compositions that contain no Qtz or Opx but contain Ne are silica undersaturated (the volume Ne-Plag-Cpx-Ol) Alkali Basalts Basanites Nephelinites and other silica undersaturated compositions lie in the silica undersaturated volume

By definition basalt is an aphanitic (fine-grained) igneous rock with generally 45-55% silica (SiO2) and less than 10% feldspathoid by volume and where at least 65% of the rock is feldspar in the form of plagioclase It is the most common volcanic rock type on Earth being a key component of oceanic crust as well as the principal volcanic rock in many mid-oceanic islands
