What is the difference between basalt and granite.

Chemical and mineralogical differences between basalt and granite. Earth contains three kinds of rocks namely igneous rocks sedimentary rocks and metamorphic rocks basalt and granite are two types of igneous rocks. Basalt chemically can be classified into tholiite transitional and alkali. All rocks of igneous origin consist of magma or molten earth that finds its way up to. Plutonic rock formed in the earth.

Igneous rocks are formed by the crystallisation of a magma. Basalt and granite actually have quite a bit in common. Properties of rock is another aspect for basalt vs andesite. The hardness of basalt is 6 and that of andesite is 7.

Basalt is available in black brown light to dark grey colors whereas andesite is available in bluish grey grey pink yellow colors. The difference is in the chemical mineralogical composition.

Granite is an intrusive rock with few contaminants while basalt is an extrusive rock with many contaminants. The main difference between them is the process through which it formed and texture. Rhyolite has a high silica content and is actually the same mineralogical composition as granite.
