Basalt is an igneous volcanic rock that forms commonly in oceanic crust and parts of continental crust.
What has more salt granite or basalt.
You can also know more about granite and basalt reserves.
Some of it erupts on land too but to a first approximation basalt is an oceanic rock.
It most commonly forms as an extrusive rock such as a lava flow but can also form in small intrusive bodies such as an igneous dike or a thin sill it has a composition similar to gabbro the difference between basalt and gabbro is that basalt is a fine grained rock while.
Compared to the familiar granite of the continents basalt ba salt is darker denser and finer grained.
What rock has more silica granite or basalt.
Basalt is more common in oceanic crust while granite is more common in continental crust.
Basalt on the other hand has a smooth texture from rapid cooling usually by water.
However basalt is considered a volcanic rock and granite is considered a plutonic rock.
Basalt is a common extrusive igneous rock formed by the rapid cooling of basaltic lava exposed at or very near the surface of earth.
Summary of basalt vs.
Basalt is the dark heavy volcanic rock that makes up most of the world s oceanic crust.
The key difference between basalt and granite is that basalt is mostly occurring on ocean floors while granite is in the crust of the earth in all continents.
Earth contains three kinds of rocks namely igneous rocks sedimentary rocks and metamorphic rocks basalt and granite are two types of igneous rocks.
Granite and basalt are both igneous rocks.
Granite is higher.
Basalts may be broadly classified on a chemical and petrographic basis into two main groups.
It forms from lava flows which extrude onto the surface and cool.
Basalt is a dark colored fine grained igneous rock composed mainly of plagioclase and pyroxene minerals.
Granite is a felsic rock meaning that it has a high silicon content.
Basalt is an aphanitic fine grained igneous rock that is relatively low in silica and alkali metals it has less than 10 feldspathoid by volume with at least 65 of the rock consisting of feldspar in the form of plagioclase this places basalt in the basalt andesite field of the qapf diagram basalt is further distinguished from andesite by its silica content of less than 52.
Basalt as a mafic rock contains more calcium oxide manganese oxide and iron compounds than granite.

All rocks of igneous origin consist of magma or molten earth that finds its way up to.
The columbia river basalt group is the youngest smallest and one of the best preserved continental flood basalt province on earth covering over 210 000 km 2 81 000 sq mi mainly eastern oregon and washington western idaho and part of northern nevada.
The basalt group includes the steen and picture gorge basalt formations.
Granite is a very hard granular crystalline igneous rock which consists mainly of quartz mica and feldspar and is often used as building stone.
