Basalt: Igneous Rock - Pictures, Definition, Uses & More

It most commonly forms as an extrusive rock, such as a lava flow, but can also form in small intrusive bodies, such as an igneous dike or a thin sill. It has a composition similar to gabbro. The difference between basalt and gabbro is that basalt is a fine-grained rock while gabbro is a coarse-grained rock.

Basalt Facts - Softschools.com

The word basalt comes from a Latin word meaning very hard stone. Though basalt is typically a dark, black rock, weathering can lead to a yellow-brown color. Basalt may also be found in various shades because of geochemical processes. A light-color basalt is rare, but can be found due to a high concentration of plagioclase and weathering.

Where is the most basalt?

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.

Basalt - Wikipedia

More than 90% of all volcanic rock on Earth is basalt. Basalt lava has a low viscosity, due to its low silica content, resulting in rapid lava flows that can spread over great areas before cooling and solidification. Flood basalt describes the formation in a series of lava basalt flows.

What Is Basalt Used For? | Reference.com

Basalt can also be cut into flags and polished and used as flooring material. To make basalt fiber, the stone is first crushed and then melted at around 2,550 degrees Fahrenheit. Then, it is poured into a machine and extruded into threads between 9 and 13 microns in diameter, which makes them thinner than human hair but not so thin they can be ...

Basalt - Wikipedia

The rock hardness of basalt is 6 on the Mohs scale, and can be seen through a combination of its compressive strength: 100-300 Mpa (Megapascal), its tensile strength: 10-30 Mpa, and its shear strength: 20-60 Mpa, which denotes that depending on the mineral makeup, basalt rocks fall in the strong - …
