In this post, we reveal everything you need to know about gabbro, including its meaning, colors, and uses. Let's get started!
When a molten rock crystallizes and solidifies, igneous rocks form. The melt starts deep under the earth, around active plate borders or hot regions, and then rises to the surface. Depending on where the molten rock hardens, igneous rocks are classified as intrusive or extrusive.
When magma is imprisoned deep within the earth, intrusive, or plutonic, igneous rock occurs. Molten rock in large globs rises to the surface. Some of the magma may fuel volcanoes on the surface, but the majority is confined beneath the surface, where it cools slowly over decades or millions of years before solidifying.
Today we will discuss one such intrusive igneous rock called ‘gabbro’.

In the 1760s, the term 'gabbro' was coined to describe a group of rock types found in the Apennine Mountains' ophiolites. Gabbro, a hamlet near Rosignano Marittimo in Tuscany, was the inspiration for the name. The word was first employed more restrictively in 1809 by German geologist Christian Leopold von Buch in his description of these Italian ophiolitic rocks. He coined the term 'gabbro' to describe rocks that geologists today refer to as 'metagabbro'.
Pyroxene and calcium-rich plagioclase make up gabbro, along with hornblende, olivine, and other minor minerals. Hornblende usually appears as a ring around augite crystals or as giant grains surrounding smaller grains of other minerals when it is present.
Geologists have identified several subtypes of gabbro. Gabbros are classified as leucogabbro, which includes less than 35% mafic minerals, meso gabbros, which contain 35 to 65% mafic minerals, and melagabbros, which contain over 65 percent mafic minerals. A rock that contains over 90% mafic minerals is classed as an ultramafic rock. Anorthosite is a gabbroic rock with less than 10% mafic mineral concentration.
Is Gabbro Mafic or Felsic?
Gabbro is a phaneritic igneous rock that is high in iron, magnesium, and calcium but low in silica. Mafic is a term used to characterize this type of rock. A mafic mineral or rock is a magnesium and iron-rich silicate mineral or igneous rock. The most frequent rock-forming mafic minerals are olivine, pyroxene, amphibole, and biotite, which are all dark. Plagioclase feldspar with a high calcium content is common in mafic rocks. Mafic minerals are sometimes known as ferromagnesian materials.
How is Gabbro Formed?
Gabbros are plutonic rocks that are chemically comparable to extrusive basalt and are generated by the cooling and crystallization of molten magma trapped beneath the earth's surface.
How to Identify Gabbro?
Here are a few factors to consider while identifying gabbro:
Hardness: One of the most useful features for identifying gabbro is the capacity to resist being scratched, often known as hardness. The capacity of one mineral to scratch another determines its hardness.
Luster: The luster of a mineral refers to how it reflects light. The basic varieties of luster are described by the phrases metallic and nonmetallic. Earthy, chalky, or dull are terms used to describe gabbro that lack luster.
Color: Color is one of a mineral's most noticeable characteristics. When identifying a gabbro, color should be considered, but it should never be used as the primary identifier.
Streaks: The color of the powdered gabbro is known as a streak, and it is usually more useful for identification than the color of the full gabbro sample.
Specific gravity: The mass (weight) of a mineral divided by the mass (weight) of an equal amount of water is known as specific gravity. The weight of a mineral in the air is divided by the weight of an equal volume of water to determine its specific gravity (SG).
Cleavage: Cleavage is the process of a gabbro breaking along smooth, flat planes. These fractures happen along with weak points in the mineral's structure. Cleavage does not exist when a mineral fractures along an uneven surface.
Fractures: Fractures are the irregular breaks that occur when a gabbro splits. Grainy, hackly (jagged), conchoidal (curved), or splintery cracks can be characterized.
Tenacity: Tenacity refers to how well a mineral resists breaking. These phrases are used to describe tenacity:
Brittle: Minerals that are brittle and break down into angular bits.
Malleable: Minerals that are malleable can be shaped and flattened into thin sheets without breaking.
Sectile: Sectile is a mineral that may be cut into thin shavings using a knife.
Flexible: Minerals are flexible, but once released, they do not revert to their original shape.
Elastic: When a mineral is released, it bends and returns to its original shape.
Where is Gabbro Found?
Gabbro is most commonly found as batholiths and laccoliths along mid-ocean ridges or in ancient mountains made primarily of compressed and elevated oceanic crust. It is found in Canada, California, and South Africa.
Gabbro vs Basalt
Gabbro is an intrusive igneous rock that originates deep under the earth's crust, and basalt is an extrusive igneous rock that occurs at or near the planet's surface. Gabbro has a coarse grain, whereas basalt has a delicate grain.
Basalt is gray to black, whereas gabbro is frequently green. Gabbro, on the other hand, is an intrusive rock and basalt is an extrusive rock. Gabbro is found deep beneath the earth's surface, whereas basalt is found at or near the surface.
Gabbro vs Diorite
Gabbro is a phaneritic, mafic intrusive igneous rock created deep beneath the earth's surface by the slow cooling of magnesium-rich and iron-rich magma into a holocrystalline mass. It cools slowly but finely and is chemically comparable to basalt. Gabbro forms near mid-ocean ridges and makes up much of the earth's marine crust.
This rock can also be found as plutons, which are related to continental volcanism. Gabbro is a name that can be used for a wide range of intrusive rocks, many of which are merely 'gabbroic', because of their varied character. Gabbro is to basalt what granite is to rhyolite, to use a crude approximation.
Diorite is an intrusive igneous rock with a moderate silica content and a low alkali metal content that forms when magma cools slowly underground. It has a composition that is halfway between low-silica gabbro and high-silica granite.
On the boundaries of continents, diorite is found in mountain-building belts. It shares the same chemical make-up as andesite, a fine-grained volcanic rock found in orogens. Since prehistoric times, diorite has been used as a decorative stone. Sargon of Akkad's Akkadian Empire used it for burial statues, and many succeeding cultures used it for sculptures and building stones.
Gabbro is available in colors like dark gray, indigo, and black.
Indigo gabbro is a crystal that is mined in Madagascar and several areas around Alaska. This stone comes in a wide range of colors, ranging from light indigo to black. Similar to the April birthstone, it is usually a black stone with gray-colored mottling that may be polished to a high gloss. When you hold this stone in the sunlight, you notice it has a stunning and unusual violet iridescence.
