Granite is lighter because its composed of felsic minerals while gabbro is made up of dark ferromagnesian minerals.
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.
Deep underground.
Yes.
the textures are similar yes but gabbro is made up of calcite and olivine while granite contains biotite mica, feldspar, and quartz.
Granite basalt pumice aplite scoria
Granite is lighter in color and higher in silicate mineral content.
Gabbro has less silica than granite.
Granite contains Quartz and Plagioclase Feldspar and Gabbro does not have neither if these minerals in it.
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.

Have a similar texture
the composition
gabbro
Deep underground.
acording to the NY state reference table for earth science; granite, pegmatite, diorite, gabbro, peridotite, and dunite
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.
