Basalt And Granite Similarities

Basalt as a mafic rock contains more calcium oxide manganese oxide and iron compounds than granite.

Basalt and granite similarities.

It wants to be there and heat is the key which unlocks the door. The trick is to heat the basalt back up again so it can melt and give the iron another shot at the core. Earth contains three kinds of rocks namely igneous rocks sedimentary rocks and metamorphic rocks basalt and granite are two types of igneous rocks. Basaltic crust is dark and thin and heavy while granite is light and accumulates.

Both are igneous rocks meaning they formed from molten rock called magma when it is underground and lava when it is on the surface and are pretty hard and dense but the similarities trail off fast from there. Gabbro is a dark medium to coarse grained intrusive igneous rock composed of calcium plagioclase pyroxene and minor olivine but no quartz. 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. It is mostly made out of quartz mica and feldspar.

Properties of rock is another aspect for basalt vs gabbro. Rhyolite is available in grey white light black colors whereas basalt is available in black brown light to dark grey colors. They also are both very common rocks on earth. Basalt is available in black brown light to dark grey colors whereas gabbro is available in dark grey to black colors.

The hardness of rhyolite is 6 7 and that of basalt is 6. Similar to gabbro is basalt which is very dark in color and features very little lightly colored crystals if any. Similarities between basalt and granite. Furthermore they are both igneous meaning that they form from direct crystallization of molten rock.

Granite is a felsic rock meaning that it has a high silicon content. All rocks of igneous origin consist of magma or molten earth that finds its way up to. As it turns out most of the ocean floor is basalt and most of the continents are 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.

The hardness of basalt is 6 and that of gabbro is 7. 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. Additionally granite is an intrusive igneous rock forming from magma cooling underground while basalt is extrusive forming from lava. Basalt and granite are both silicate rocks which contain common minerals such as feldspar and pyroxene.

Similarities between granite and basalt. Appearance of basalt is dull and soft and that of gabbro is veined and shiny. Its high iron content gives it magnetic properties and it may show signs of rust when exposed to air.
