Basalt vs Gabbro - What's the difference? | WikiDiff

As nouns the difference between basalt and gabbro is that basalt is (mineral) a hard mafic igneous rock of varied mineral content; volcanic in origin, it makes up much of the earth's oceanic crust while gabbro is (rock) a name originally given to a kind of serpentine, and now generally used for a coarsely crystalline, igneous rock consisting of lamellar pyroxene and labradorite.

Gabbro - an overview | ScienceDirect Topics

Gabbro is mafic, intrusive, coarse-grained rock with allotriomorphic texture. Gabbros contain mainly ferromagnesian minerals and plagioclase, the amount of ferromagnesian minerals equaling or exceeding that of the plagioclase. Gabbros are plutonic rocks formed by cooling and crystallization of molten magma trapped under the Earth's surface and chemically equivalent to extrusive basalt.

Pictures and Descriptions of Igneous Rock Types

Igneous rocks are those that form via the process of melting and cooling. If they erupt from volcanoes as lava, they are called extrusive rocks.If they cool underground but near the surface, they are called intrusive and often have visible, but tiny mineral grains.If they cool very slowly deep underground, they are called plutonic and have large mineral grains.

Igneous Rocks | Pictures of Intrusive and Extrusive Rock Types

What are Igneous Rocks? Igneous rocks are formed from the solidification of molten rock material. There are two basic types. Intrusive igneous rocks crystallize below Earth's surface, and the slow cooling that occurs there allows large crystals to form. Examples of intrusive igneous rocks are diorite, gabbro, granite, pegmatite, and peridotite. ...
