- Gabbro - Wikipedia
Gabbro is a coarse-grained (phaneritic) 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 is a type of intrusive igneous rock that is coarse-grained and dark-colored, typically composed of calcium-rich plagioclase feldspar, pyroxene, and sometimes olivine It is similar in composition to basalt, which is its extrusive equivalent

- Gabbro - Geology is the Way
Gabbro is a plutonic igneous rock and the intrusive counterpart of basalt The name ‘gabbro’ derives from the Italian town of Gabbro (Rosignano Marittimo, Tuscany) and was first coined by the Italian geologist Tozzetti in 1768 Tozzetti used the term to refer to a suite of ophiolitic rocks
