Does gabbro have a higher silica content than granite?
Gabbro has less silica than granite.
What minerals are in granite but not gabbro?
Granite contains Quartz and Plagioclase Feldspar and Gabbro does not have neither if these minerals in it.
Granite and gabbro have?
Have a similar texture
What are examples of intrusive rocks?
acording to the NY state reference table for earth science; granite, pegmatite, diorite, gabbro, peridotite, and dunite
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.

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.
Granite and gabbro have?
Have a similar texture
What is lighter gabbro or granite?
Granite is lighter because its composed of felsic minerals while gabbro is made up of dark ferromagnesian minerals.
It is sometimes called black granite?
gabbro
Where do granite and gabbro crystallize?
Deep underground.
Do Granite and Gabbro have the same chemical composition?
No. Gabbro is a mafic rock (magnesium and iron silicates) while granite is a felsic rock (referring to lighter elements such as potassium in feldspar). Felsic rock contains fewer heavy elements than mafic rocks. The chemical equivalent to gabbro is basalt, as both are mainly pyroxene and plagioclase feldspar. The difference is that gabbro is intrusive rock and basalt is extrusive.

What rock is not affected by acid rain?
granite and gabbro
Do granite and gabbro have similar crystal size?
Yes.
