Gabbro is a ingenious rock from portions of Canada. It is estimated to be well over a billion years old and one of the oldest types of rock.
Gabbro is an intrusive igneous rock that is dark and coarse-grained and has a crystalline structure. Gabbro took millions of years to cool from magma into igneous rock.
Gabbro is an intrusive mafic igneous rock. A dike is a type intrusive igneous structure and is not associated with any particular type of igneousn rock. Gabbro can form dikes, sills, and other structures.
Gabbro has much larger grains that basalt does. This is because basalt cools faster than gabbro and has less time to form crystals.
Gabbro is coarse textured.
Although gabbro is low in silica and has no quartz there are quartz gabbro's. Quartz gabbro's are thought to occur from magma that was over-saturated with silica.

Gabbro is an igneous, plutonic rock, formed when magma is trapped under the Earth's surface and cools into a crystalline form. A large portion of the Earth is underlain by gabbro within the oceanic crust.
Gabbro has much larger grains that basalt does. This is because basalt cools faster than gabbro and has less time to form crystals.
Gabbro is a group of dark, coarse-grained, intrusive mafic igneous rocks. They are often found beneath the Earth's surface where they form into crystals.
The magma cools and forms both rocks
Yes. For example gabbro and basalt are chemically equivalent (and so are composed of the same minerals), however gabbro is intrusive and basalt is extrusive.
Gabbro is a rock
Gabbro is coarse textured.
No. Gabbro is an intrusive igneous rock.
Although gabbro is low in silica and has no quartz there are quartz gabbro's. Quartz gabbro's are thought to occur from magma that was over-saturated with silica.
Basalt or gabbro. Mafic igneous rock.
