Granite contains Quartz and Plagioclase Feldspar and Gabbro does not have neither if these minerals in it.
Granite is an igneous rock with a coarse-grained texture that is typically light in color and contains quartz, feldspar, and mica minerals. Gabbro is also an igneous rock but has a finer-grained texture and is dark in color, composed mainly of plagioclase feldspar and pyroxene minerals. Overall, granite is lighter in color and coarser-grained compared to gabbro.
Basalt and gabbro have higher chemical weathering rates than rhyolite and granite because they contain more ferromagnesian minerals like olivine and pyroxene that are more susceptible to chemical weathering compared to the quartz-rich minerals in rhyolite and granite. This makes basalt and gabbro more prone to breakdown and alteration when exposed to weathering agents like water and acids.
No, gabbro has a lower silica content than granite. Gabbro is classified as a mafic rock with silica content ranging from 45-52%, while granite is a felsic rock with higher silica content ranging from 65-75%.

No, gabbro is not a felsic rock. Gabbro is classified as a mafic rock due to its dark color and high content of iron and magnesium minerals, while felsic rocks are light-colored and have a higher silica content.
Gabbro is typically lighter than granite because it has a higher density due to its composition of minerals such as pyroxene and plagioclase feldspar. Granite is composed of minerals like quartz, feldspar, and mica, which generally have lower densities.
Granite, gabbro, and diorite are all igneous rocks formed from the cooling and solidification of molten magma. They are composed of minerals such as feldspar, quartz, and mica. The difference between them lies in their mineral composition and texture, with granite containing mostly light-colored minerals, gabbro containing mostly dark-colored minerals, and diorite having a balanced mix of light and dark minerals.
Never say never, but it's mica.

Both gabbro and granite are igneous rocks, but they have different mineral compositions and textures. Gabbro is dark in color and consists mainly of pyroxene, plagioclase feldspar, and olivine minerals, with a coarse-grained texture. Granite, on the other hand, is light in color and composed mainly of quartz, feldspar, and mica minerals, with a medium to coarse-grained texture.
Gabbro is mafic intrusive igneous rock and contains olivine, pyroxene, plagioclase and amphibole. These minerals are unstable at low pressure temperature conditions. In contrast, granite is felsic intrusive igneous rock and contains high amounts of quartz and orthoclase. Stability of minerals are increasing top to bottom in Bowen's Reaction Series.
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.
No, gabbro has a lower silica content than granite. Gabbro is classified as a mafic rock with silica content ranging from 45-52%, while granite is a felsic rock with higher silica content ranging from 65-75%.
granite and gabbro
Gabbro is usually made up of minerals such as pyroxene, plagioclase, amphibole and olivine which makes it an intrusive igneous rock.
Granite and gabbro both contain large crystals, but gabbro typically has larger crystals due to its slower cooling rate beneath the Earth's surface compared to granite which cools at or near the surface.
