Gabbro is a medium-grained, ultramafic igneous rock. It is made up of plagioclase feldspar and pyroxene. Gabbro is an intrusive igneous rock, meaning that it forms from the solidification of magma within the earth. Intrusive igneous rocks are medium- to coarse-grained because they cool slowly over time

Where is basalt and gabbro formed?
Basalt and gabbro are chemically equivalent rocks. Basalt solidifies above ground and gabbro solidifies below ground.
What is the difference between gabbro and basalt?
Gabbro is an intrusive rock, which means it formed underground. Basalt is an extrusive rock, which means it formed above ground .
Is gabbro an intrusive or extrusive igneous rock?
Gabbro is an intrusive igneous rock, whick means that it was formed under ground.
What are some examples of intrusive igneous rock?
Granite and gabbro are the two biggies, granite being formed underground by felsic magma, and gabbro being formed underground by mafic magma. Diorite and peridotite are two others.
What are the parent rocks of gabbro?
Gabbro is an igneous rock, and therefore does not have a parent rock as would a metamorphic rock. Gabbro is an intrusive igneous rock formed from the slow cooling and solidification of mafic magmas deep underground.
Where is basalt and gabbro formed?
Basalt and gabbro are chemically equivalent rocks. Basalt solidifies above ground and gabbro solidifies below ground.
Is gabbro made from magma that cooled slowly?
Gabbro is formed from slow cooling basaltic magma.
What is the difference between gabbro and basalt?
Gabbro is an intrusive rock, which means it formed underground. Basalt is an extrusive rock, which means it formed above ground .
Is gabbro an intrusive or extrusive igneous rock?

Where is gabbro found in the earth?
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.
What are the parent rocks of gabbro?
Gabbro is an igneous rock, and therefore does not have a parent rock as would a metamorphic rock. Gabbro is an intrusive igneous rock formed from the slow cooling and solidification of mafic magmas deep underground.
What are two igneous rocks formed from slow cooling magma?
Granite and Gabbro.
Where in the world is gabbro found?
Gabbro is an igneous rock with an intrusive origin. This means that the rock was formed when a body of magma pushed its way into the Earth's crust and formed an intrusion. This magma eventually cools and forms a coarse grained intrusive igneous rock. Gabbro can be found anywhere that a body of magma has risen and cooled.
Clay minerals formed from gabbro or diorite bedrock illustrate what kind of weathering?
Chemical Weathering.
What kind of igneous rock is mafic and formed deep in the ground?
Gabbro is mafic and forms underground.
What formed ocean crust?
Ocean crust is formed by intrusive magma at mid-ocean-ridges. The magma cools and solidifies into peridotite, basalt, or gabbro.
