Main Differences Between Granite And Basalt

Granite is lighter in color than basalt.

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. Basalt and granite actually have quite a bit in common. Basalt is volcanic or extrusive forming at the surface while granite is plutonic or intrusive forming beneath the surface. All rocks of igneous origin consist of magma or molten earth that finds its way up to.

Andesite s come from shallow sources near the continental. 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 between basalt lava and andesite lava is the chemical composition. 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.

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

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. Gabbro is a dark medium to coarse grained intrusive igneous rock composed of calcium plagioclase pyroxene and minor olivine but no quartz. 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 lava comes from deep in the mantle of the earth.

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. Basalt rocks have fine grained crystals while gabbro is made up of much larger coarse grained pieces. What s the most obvious difference between basalt and gabbro.
