Mafic is a term used to describe an igneous rock that is usually dark in color, with a chemistry that may be high in magnesium and iron, like basalt. Mafic is also a term used to describe a type of magma that is high in calcium, magnesium and iron, and relatively low in silica, compared to felsic magma.
What else can I help you with?
Is olivine mafic or felsic?
Olivine is a mafic mineral. It is most abundant in ultramafic rocks.
Is quartz mafic?
No, quartz is not mafic. Mafic minerals are rich in magnesium and iron, while quartz is a silicate mineral composed of silicon and oxygen. Quartz is classified as a felsic mineral due to its composition and low mafic content.
What are mafic rocks?
A mafic rock is composed of mafic minerals such as biotite mica, amphibole, proxene, and olivine. The actual word mafic refers to magnesium and iron; nevertheless, these minerals are called ferromagnesian. Mafic rocks include gabbro, scoria, and basalt. They each have about 46-85% mafic mineral crystals. Periodite, 86-100% mafic minerals, is considered ultramafic because of its olivine composition.
What minerals are found in mafic rocks?
mafic rocks can be made up of orthoclase feldspar and quartz
Is granite mafic?
No, granite is not considered mafic. It is an igneous rock that is classified as felsic due to its high silica content and lower concentration of iron and magnesium minerals compared to mafic rocks like basalt.
What is the difference between felid and mafic?
Felsic rocks have 0-15% mafic crystals, while mafic rocks have 46-85% mafic crystals.
Is the oceanic crust felsic or mafic?

Is a limestone mafic?
No. The terms mafic and felsic apply to igneous rocks. Limestone is a sedimentary/biochemical rock and so cannot be said to be mafic, felsic, or intermediate.

The types of magma?
Felsic, intermediate, mafic and ultra mafic are the four broad types of magma.
