Main Differences Between Granite And Basalt

Andesite s come from shallow sources near the continental.

Main differences between granite and basalt.

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. Granite is the principal component of the continental crust while basalt is the principal component of the oceanic crust. What s the most obvious difference between basalt and gabbro. Granite is lighter in color than basalt.

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. Gabbro is a dark medium to coarse grained intrusive igneous rock composed of calcium plagioclase pyroxene and minor olivine but no quartz. 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.

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 and granite actually have quite a bit in common. 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. Basalt lava comes from deep in the mantle of the earth.

Basalt is basic and contains a substantial amount of olivine whereas granite is. The main difference between basalt and rhyolite is that basalt usually appears in dark colours while rhyolite usually appears in light colours. Granite is an intrusive rock with few contaminants while basalt is an extrusive rock with many contaminants. The color of the rocks is dependent on the mineral composition of the rock.

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 difference between basalt lava and andesite lava is the chemical composition. All rocks of igneous origin consist of magma or molten earth that finds its way up to.
