Gabbro - Wikipedia
Gabbro is a coarse-grained igneous rock that is relatively low in silica and rich in iron, magnesium, and calcium. Such rock is described as mafic. Gabbro is composed of pyroxene (mostly clinopyroxene) and calcium-rich plagioclase, with minor amounts of hornblende, olivine, orthopyroxene and accessory minerals. [4]

Gabbro | Igneous Rock, Mafic Minerals & Plutonic Intrusions
gabbro, any of several medium- or coarse-grained rocks that consist primarily of plagioclase feldspar and pyroxene. Essentially, gabbro is the intrusive (plutonic) equivalent of basalt, but whereas basalt is often remarkably homogeneous in mineralogy and composition, gabbros are exceedingly variable.

Gabbro - Geology is the Way
Gabbro is a plutonic igneous rock and the intrusive counterpart of basalt. Gabbros are essentially constituted by Calcium-rich plagioclase (>An50), clinopyroxene (augite, diopside), and iron oxides (ilmenite, magnetite) and may contain accessory olivine, amphibole, orthopyroxene, and spinel.
