Difference Between Granite And Basalt Rocks

Basalt and granite are both silicate rocks which contain common minerals such as feldspar and pyroxene.

Difference between granite and basalt rocks. Volcanic in origin it makes up much of the earth s oceanic crust while granite is a group of igneous and plutonic rocks composed primarily of feldspar and quartz usually contains one or more dark minerals which may be mica pyroxene or amphibole granite is. 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. Granite is a felsic rock meaning that it has a high silicon content. They will probably conclude that the tektite is most similar to basalt or obsidian because both samples will be black in color and contain visible minerals.

Granite basalt obsidian sandstone and schist. Granite is lighter in color than basalt. They also are both very common rocks on earth. 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.

The color of the rocks is dependent on the mineral composition of the rock. All rocks of igneous origin consist of magma or molten earth that finds its way up to. Common minerals include quartz feldspar mica amphibole olivine and calcite a rock is an aggregate of one or more minerals or a body of undifferentiated mineral matter. Basalt as a mafic rock contains more calcium oxide manganese oxide and iron compounds than granite.

Granite is an igneous rock whereas gneiss is formed after metamorphosis of an existing igneous rock. Furthermore they are both igneous meaning that they form from direct crystallization of molten rock. It is mostly made out of quartz mica and feldspar. A mineral is a naturally occurring inorganic element or compound having an orderly internal structure and characteristic chemical composition crystal form and physical properties.

The mineral composition of both granite and gneiss is same but alteration of granite because of very high pressure and temperature leads to the formation of gneiss. As nouns the difference between basalt and granite is that basalt is mineral a hard mafic igneous rock of varied mineral content. 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. Basalt is basic and contains a substantial amount of olivine whereas granite is.

In this lab the students will compare samples of tektites with five earth rocks. Earth contains three kinds of rocks namely igneous rocks sedimentary rocks and metamorphic rocks basalt and granite are two types of igneous rocks. Similarities between basalt and granite. 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.

Differences between basalt and granite. Its high iron content gives it magnetic properties and it may show signs of rust when exposed to air.
