thumbnail|Basalt Mafic is a term used in geology to describe silicate minerals, magmas, and igneous rocks that are rich in magnesium and iron, while being relatively low in silica content. Most mafic minerals are dark in color, and common rock-forming mafic minerals include olivine, pyroxene, amphibole, and biotite. Common mafic rocks include basalt, diabase and gabbro. Mafic rocks often also contain calcium-rich varieties of plagioclase feldspar. Mafic materials can also be described as ferromagnesian.

Il termine femico deriva dalla associazione delle parole ferro e magnesio e sta appunto a indicare quei minerali componenti le rocce magmatiche che sono ricchi di composti di questi elementi. Talvolta viene usato il termine mafico che deriva dalla stessa associazione ferro-magnesio proposta ed è in effetti un sinonimo preferito dai petrografi della scuola anglosassone.
