It is a major constituent of lava flows on the surface and of the ocean bottoms.

Common mafic rocks are granit.

Crystalline rocks with obsidian’s composition include granite and rhyolite. Both granite and quartzite are very hard, but on the mohs scale of hardness (from 1 to 10, with 10 being hardest) quartzite has the slight edge. (or mafic) the most abundant rock of all kinds that forms ocean floors granitic (or felsic) granite is the second most abundant rock, as continents are primarily comprised of granite.

Cooling rate directly affects grain size of an igneous rock. Common mafic rocks include basalt and gabbro. Both are igneous rocks, which means that they cooled from a magma (the earth gets very hot just below the surface, and there is lots of liquid rock available).

It is in fact the most common extrusive igneous rock. Diorite was used extensively by ancient civilizations for vases and other decorative artwork and is still used for art today (figure 1). In the photo of granite below (figure 6.4), the quartz is gray and the feldspar is salmon colored.

It is usually water for a liquid or solid, and air for a gas.) Granite is the most common felsic rock. When we divide the igneous rocks on the basis of silica content, mafic rocks stand at 3rd rank in terms of it i.e 45 to 55% silica content and they are dark colour rocks in which most common mafic minerals are olivine, pyroxene, amphibole, and biotite.

How is granite formed easy? The mantle is predominantly made up of an ultramafic rock known as. Over most of the continents, this granite is hidden below a thin layer of sedimentary rock.

These minerals are high in magnesium and ferric oxides, and their presence gives mafic rock its characteristic dark colour. One important use is as stone for buildings and statues. It is also known to be a mnemonic, combining (fe) for feldspar, (l) for lenad or feldspathoid, and (s) for silica.
