Bazalt Stone is a fine-grained, dark-colored igneous rock that is mostly made up of plagioclase and pyroxene minerals. It usually appears as an extrusive rock, such as lava, but it can also appear in small intrusive bodies, such as an igneous dike or a thin sill. It has a similar composition to gabbro. Basalt and gabbro differ in that basalt is a fine-grained rock, whereas gabbro is a coarse-grained rock.
Basalt underlies more of Earth’s surface than any other rock type. Most areas within Earth’s ocean basins are by basalt. Although basalt is much less common on continents, lava flows and flood basalts underlie several percent of Earth’s land surface. Bazalt Stone is a very important rock.
On the Moon, basalt is likewise plentiful. Basalt lava flows and flood basalts cover a large portion of the Moon’s surface. The term “lunar maria” refers to these Moon regions. Extensive basalt flows have resurfaced large regions of the Moon, possibly as a result of catastrophic impact events.
We utilize basalt for a wide range of applications. Crushed for use as aggregate in construction projects is the most typical use. We use crushed basalt for a variety of applications, including road base, concrete aggregate, asphalt pavement aggregate, railroad ballast, drain field filter stone, and more. Dimension stone comes from basalt. Basalt is carved into thin slabs and polished to make floor tiles, building veneer, monuments, and other stone artifacts.
