Basalt chemically can be classified into tholiite transitional and alkali.
Chemical and mineralogical differences 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.
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.
All rocks of igneous origin consist of magma or molten earth that finds its way up to.
Properties of rock is another aspect for basalt vs andesite.
Basalt is volcanic or extrusive forming at the surface while granite is plutonic or intrusive forming beneath the surface.
Igneous rocks are formed by the crystallisation of a magma.
Rhyolite has a high silica content and is actually the same mineralogical composition as granite.
Rhyolite is to granite what basalt.
The difference between granites and basalts is in silica content and their rates of cooling.
Home science earth science geology what is the difference between basalt and granite.
The hardness of basalt is 6 and that of andesite is 7.
Appearance of basalt is dull and soft and that of andesite is dull and soft.
Basalt is an extrusive fine grained igneous rock formed when the molten materials lava r.
What is the difference 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.
The difference is in the chemical mineralogical composition.
Basalt and granite actually have quite a bit in common.
A basalt is about 53 sio2 whereas granite is 73.
Basalt and gabbro are both mafic igneous rocks having same mineralogy.
The main difference between them is the process through which it formed and texture.
Granite is an intrusive rock with few contaminants while basalt is an extrusive rock with many contaminants.
Differences between basalt and granite although there are some similarities between basalt and granite there are also significant differences between these two rock types.
Both rhyolite and basalt are extrusive igneous rocks because they came from melts that cooled on the earth s surface rather than deep underground.
Intrusive slowly cooled inside the crust.
Earth contains three kinds of rocks namely igneous rocks sedimentary rocks and metamorphic rocks basalt and granite are two types of igneous rocks.
