  1. Gabbro

    Gabbro () is a phaneritic (coarse-grained), mafic intrusive igneous rock formed from the slow cooling of magnesium-rich and iron-rich magma into a holocrystalline mass deep beneath the Earth's surface. Slow-cooling, coarse-grained gabbro is chemically equivalent to rapid-cooling, fine-grained basalt. Much of the Earth's oceanic crust is made of gabbro, formed at mid-ocean ridges. Gabbro is also found as plutons associated with continental volcanism. Due to its variant nature, the term gabbro may be applied loosely to a wide range of intrusive rocks, many of which are merely "gabbroic". By rough analogy, gabbro is to basalt as granite is to rhyolite.


  1. gabbro

    Gabbro is a type of dark, coarse-grained igneous rock that is intruded beneath the earth's surface. It is composed mainly of the minerals plagioclase feldspar and pyroxene, and may also contain small amounts of olivine or amphibole. It is similar in composition to basalt but is formed under different conditions. Gabbro is often used as a construction material due to its durability.

Webster Dictionary

  1. Gabbronoun

    a name originally given by the Italians to a kind of serpentine, later to the rock called euphotide, and now generally used for a coarsely crystalline, igneous rock consisting of lamellar pyroxene (diallage) and labradorite, with sometimes chrysolite (olivine gabbro)

  2. Etymology: [It.]


  1. Gabbro

    Gabbro refers to a large group of dark, coarse-grained, intrusive mafic igneous rocks chemically equivalent to basalt. The rocks are plutonic, formed when molten magma is trapped beneath the Earth's surface and cools into a crystalline mass. The vast majority of the Earth's surface is underlain by gabbro within the oceanic crust, produced by basalt magmatism at mid-ocean ridges.

Chambers 20th Century Dictionary

  1. Gabbro

    gab′ro, n. a rock composed of feldspar and diallage—also Euphotide.—n. Gabb′ronite, a compact variety of scapolite, resembling gabbro. [It.]
