What are the main differences between granite and basalt.

Aug 14 2011 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. Granite is a medium tocoarse grained acid igneous rock with essential quartz 20 and feldspar where alkali feldspar constitutes between 100 and 35 of the feldspars and minor mafic minerals hornblende and biotite are the commonest mafic minerals however muscovite is also frequently encountered. What is the main difference between granite and basalt. What s the most obvious difference between basalt and gabbro.

Basalt and granite actually have quite a bit in common. 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. Basalt is a dark colored fine grained igneous rock composed mainly of plagioclase and pyroxene minerals. In the category of felsic higher silica content of magma.

All rocks of igneous origin consist of magma or molten earth that finds its way up to. Earth contains three kinds of rocks namely igneous rocks sedimentary rocks and metamorphic rocks basalt and granite are two types of igneous rocks. Granite is the principal component of the continental crust while basalt is the principal component of the oceanic crust. 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 volcanic or extrusive forming at the surface while granite is plutonic or intrusive forming beneath the surface. Like gabbro granite and diorite basalt is an igneous rock and is also the most abundant bedrock on earth including under the surface and within ocean basins. Differences between basalt and granite although there are some similarities between basalt and granite there are also significant differences between these two rock types. 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.

Both rhyolite and basalt are types of igneous rocks igneous rocks are usually found in two forms as intrusive and extrusive igneous rocks based on the method of formation. Basalt rocks have fine grained crystals while gabbro is made up of much larger coarse grained pieces. Earth contains three kinds of rocks namely igneous rocks sedimentary rocks and metamorphic rocks basalt and granite are two types of igneous rocks. The main difference between basalt and rhyolite is that basalt usually appears in dark colours while rhyolite usually appears in light colours.

Pyroxene andalusite corundum tourmaline garnet and topaz are also relatively common mafic. Smaller in size not able to see as well as granite.
