Basalt records the orientation of the magnetic field of the earth which shows that the magnetic field of the earth is continually changing.

The iron particles found in the ocean floor are called Basalt and are made of high-density materials.

Basalt is an igneous rock that is formed from the quick cooling of lava rich in magnesium and iron when exposed at or very near the surface of a terrestrial planet or the moon. Basalt rocks are usually formed when the volcanic basaltic Lava rapidly cools from the deep interior of the earth's crust equivalent to plutonic gabbro-norite magma and gets exposed to the Earth surface. Gas cavities are absent in the basalt lows and these floors are generally quite thick and extensive.

Rock Hardness property is usually measured to determine the compressive fracture strength, to determine whether a rock is a soft rock or a hard rock. Rock hardness property is common among the densest, fine-grained textured rocks, such as basalt.

Basalt rocks are mainly composed of pyroxene olivine and plagioclase, these rocks are rich in Magnesium and iron. The most porphyritic minerals in basalt rocks are augite and olivine. Basaltic lavas are pumiceous and spongy.
