The cavities on the surface of basalt filled with different minerals like calcite, chalcedony or zeolite in the long run. Basalt types that compromise olivine named as olivine basalt and the basalt types that compromise sodium named as sodium basalt. There are also rare basalt types in nature that compromise quartz or brown mica in nature.
What is Basalt? - Definition, Uses & Composition. ... Basalt is a typically dark-colored, extrusive igneous rock, and igneous means that it formed from rapidly-cooled lava on the earth's surface.
Basalt is Earth's most abundant bedrock, and a very important rock. The Earth's ocean basins are underlain by basalt, but it is less common on continents. However, lava flows and flood basalts underlie several percent of Earth's land surface. It is an igneous rock and is usually fine-grained and dark-colored, composed mainly of plagioclase and pyroxene minerals.
Basalt is a mafic volcanic rock consisting primarily of plagioclase feldspar and pyroxene minerals. Common accessory minerals can include other pyroxenes, olivine, quartz, and nepheline. Basalt is the volcanic equivalent of the plutonic rock gabbro, and as such has a low silica content (48% – 52%).
Basalt is a common grey to black extrusive volcanic rock.It is usually fine-grained because of its rapid cooling of lava on the Earth's surface.. Unweathered basalt is black or grey. Basalt blocks are often used for roads and pavements (sidewalks).

Gabbro in Oceanic Crust. It is often stated that Earth's oceanic crust is made up of basalt. The word "basalt" is used because the rocks of the oceanic crust have a "basaltic" composition. However, only a thin surface veneer of oceanic crust is basalt. The deeper rocks of the oceanic crust are generally coarser-grained gabbro.
Fun Facts About Igneous Rocks for Kids. The ocean floor is usually made of basalt rock, a hard, black, extrusive rock. Lava fields in Hawaii cool to form basalt rock. Rhyolite is similar to granite but it comes from volcanic lava. It is lighter in weight than granite, which is very dense.
Basalt is a hub for mountain biking in the Roaring Fork valley. There are a dozen world class cross country trails as well as lift-accessed downhilling within 15 miles of Basalt, both up and down the valley. Transportation. Roaring Fork Transportation Authority (RFTA) provides bus transit in Basalt.

Igneous Rocks Facts. Igneous comes from the Latin word ... Basalt forms when lava cools quickly. Most of the ocean floor and the Hawaiian Islands are made of basalt. It is also found on the Moon, Venus and Mars. Because it is a common rock and very hard, people used basalt for early choppers and for grinding stones to grind grains like millet ...
Jun 12, 2014· 1. Textile applications for fire protection Basalt does not melt nor shrink in the flame and, when not mechanically stressed, keeps its geometric integrity. When coming to heat resistance, Basalt is exceptionally suited to block fire. Basalt products resist the open flame. Basalt melts at ca. 1450 C. A fabric made of Basalt, with a […]
Interesting Facts. Ninety-five percent of the Earth's crust is made of igneous rock. Wow, that’s a lot. There are over 700 different kinds of igneous rocks that have been identified so far. Do you think there’s more? The ocean floor is normally made out of basalt rock, …
Lunar Rocks. The Apollo lunar landings yielded an abundance of new scientific data on the Moon. The various experiments placed on the surface provided information on seismic, gravitational, and other lunar characteristics. But perhaps the most dramatic result of the missions was returning a total of more than 800 pounds of lunar rock and soil ...
Basalt is a very common igneous rock. In fact it is the most common rock in the Earth's crust. Almost all oceanic crust is made of basalt and basalt is a common extrusion from many volcanic regions around the world. It forms from the melting of the upper mantle and its chemistry closely resembles the upper mantle's composition.
Basalt: Basalt, extrusive igneous (volcanic) rock that is low in silica content, dark in color, and comparatively rich in iron and magnesium. Basalts may be broadly classified on a chemical and petrographic basis into two main groups: the tholeiitic and the alkali basalts. Learn more about basalt …
