Chemical And Mineralogical Differences Between Basalt And Granite

Basalt is available in black brown light to dark grey colors whereas andesite is available in bluish grey grey pink yellow colors.

Chemical and mineralogical differences between basalt and granite.

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. Intrusive slowly cooled inside the crust. Both rhyolite and basalt are extrusive igneous rocks because they came from melts that cooled on the earth s surface rather than deep underground. Basalt and granite actually have quite a bit in common.

Basalt and gabbro are both mafic igneous rocks having same mineralogy. Basalt is an extrusive fine grained igneous rock formed when the molten materials lava r. Continental crust density 2 7 2 8. Igneous rocks are formed by the crystallisation of a magma.

A basalt is about 53 sio2 whereas granite is 73. By staff writer last updated apr 4 2020 5 22 03 am et. Home science earth science geology what is the difference between basalt and granite. We are defined within the range of rock basalt from 48 52 sio2.

The difference between granites and basalts is in silica content and their rates of cooling. Rhyolite is to granite what basalt. 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 hardness of basalt is 6 and that of andesite is 7.

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 an intrusive rock with few contaminants while basalt is an extrusive rock with many contaminants. What is the difference between basalt and granite. Basalt is volcanic or extrusive forming at the surface while granite is plutonic or intrusive forming beneath the surface.

Earth contains three kinds of rocks namely igneous rocks sedimentary rocks and metamorphic rocks basalt and granite are two types of igneous rocks. The difference is in the chemical mineralogical composition. All rocks of igneous origin consist of magma or molten earth that finds its way up to. Rhyolite has a high silica content and is actually the same mineralogical composition as granite.

Cite 20th jul 2018. Basalt chemically can be classified into tholiite transitional and alkali. Properties of rock is another aspect for basalt vs andesite. The main difference between them is the process through which it formed and texture.
