What is the fine grained equivalent of gabbro?
Dolerite
What are four Mafic Igneous rocks?
The four I know of are: gabbro, basalt, peridotite, and dolerite.
What is a dolerite dyke?
Dolerite is coarse grained variety of basalt, if present in the dorm of a dyke (discordent igneous body), it is called a dolerite dyke.
Is dolerite magnetic?
Yes, it can be.
How much gabbro is in olivine?
Olivine does not contain Gabbro. Gabbro can contain olivine. Usually no more than a few percent.
What is the fine grained equivalent of gabbro?
Dolerite
What are four igneous rocks?
The four I know of are: gabbro, basalt, peridotite, and dolerite.
Dolerite and gabbro are both igneous rocks Dolerite has crystals about 1 mm across and gabbro has crystals about 5 mm across What does this indicate about the formation of these rocks?
In comparison to the slower cooled magma that created the gabbro, the dolerite has formed closer to the surface. This means that there was less time for crystal growth before it cooled into rock, resulting in the difference in crystal size between the two.

Which is a coarse-grained igneous rock composed of mainly pyroxene plagioclase feldspar and olivine?
Gabbro.
How do gabbro and pumice differ in texture and density?
have differnt made up marerials
How does a Granite rock and a Gabbro rock differ from each other?
The counterpart of Granite is Rhyolite,the counterpart of Gabbro is Basalt. Gabbro is mafic(Dark coloured) ,Granite is felsic (light coloured) Granite forms from magma of Granitic composition while Gabbro forms from magma of Basaltic composition.
How does a basalt differ from gabbro?
Gabbro has much larger grains that basalt does. This is because basalt cools faster than gabbro and has less time to form crystals.
How does granite differ from gabbro in coloring and silica content?
Granite is lighter in color and higher in silicate mineral content.
Is Dolerite Rock rough or smooth?
Dolerite is very rough.
What is a dolerite dyke?
