Is basalt more common than granite.

Granite is a very hard granular crystalline igneous rock which consists mainly of quartz mica and feldspar and is often used as building stone. Granite is a felsic rock meaning that it has a high silicon content. The fine grained equivalent of gabbro is basalt. Basalt and granite actually have quite a bit in common.

The tholeiitic and the alkali basalts. Lava is magma on the earth surface. Basalt as a mafic rock contains more calcium oxide manganese oxide and iron compounds than granite. It is mostly made out of quartz mica and feldspar.

Excluding the rocks between my ears i d have to say that basalt and granite have the honor of being the most important rocks in the crust. 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. Basalt is the most common continental crustal rock. Summary of basalt vs.

It forms from lava flows which extrude onto the surface and cool. Compared to the familiar granite of the continents basalt ba salt is darker denser and finer grained. Extrusive rocks cool slowly creating coarse grained igneous rocks. Its high iron content gives it magnetic properties and it may show signs of rust when exposed to air.

Basalt is a common extrusive igneous rock formed by the rapid cooling of basaltic lava exposed at or very near the surface of earth. Although basalt is much less common on continents lava flows and flood basalts underlie several percent of earth s land surface. Basalt is more common in oceanic crust while granite is more common in continental crust. Therefore more basalt than gabbro and more granite than rhyolite.

Mafic magmas crystallize to form relatively simple atomic structures isolated tetrahedra and single chains and therefore flow easily the higher mafic temperatures also contribute to this ease of.

Another reason is the internal crystalline structure of the silicate minerals. Some of it erupts on land too but to a first approximation basalt is an oceanic rock. Basalt is a very important rock. Basalt is an igneous volcanic rock that forms commonly in oceanic crust and parts of continental crust.

Basalt extrusive igneous volcanic rock that is low in silica content dark in color and comparatively rich in iron and magnesium. Earth contains three kinds of rocks namely igneous rocks sedimentary rocks and metamorphic rocks basalt and granite are two types of igneous rocks. Most areas within earth s ocean basins are underlain by basalt. All rocks of igneous origin consist of magma or molten earth that finds its way up to.
