Basalt is an igneous rock. Plate tectonics causes some areas of the crust to separate, and mafic magma from the upper mantle is allowed to move to the surface and erupt as a volcano. Because basalt is mafic, it is generally heavier than the granitic rocks that make up the continents.

Normal magnetite is attracted to a magnet, but some specimens are automagnetized and have the ability to attract small pieces of iron, small pieces of magnetite, and other magnetic objects. This form of magnetite, known as "lodestone," was man''s first encounter with the property of magnetism.
Types of Igneous Rocks in Minnesota. BASALT. About billion years ago, the continent that had been building for billions of years began to split apart across what is now Minnesota. The "Midcontinent rift," is where the crust began to separate to form a new ocean basin, but stopped short of actually making a .

Fragments of a 2 billion ton object would likely become nearly as cheap as regular basalt, which is in almost limitless supply: For reference, it takes a single volcano (Kilauea) in Hawaii only about 7 years to erupt 1 km3 of basalt, and nearly the entire ocean seafloor is made of basalt.

Felsic igneous rocks, as a whole rock, tend to have light colors or shades: white, pink, light brown, light gray. Mafic igneous rocks, on the whole, tend to be dark colored, commonly black or dark gray. Most mafic magma originates by melting of rocks in the mantle that are extremely rich in iron and magnesium.

Basalt is not related to hot temperatures any more than the other igneous rocks, however, basalt is more related to volcanic activity than rocks like granite. This diagram shows the conditions which make igneous rocks (Mafic rocks have higher iron content and felsic rocks have higher quartz, and extrusive/intrusive refers to the cooling rate).
