Basalt is a common extrusive igneous rock formed by the rapid cooling of basaltic lava exposed at or very near the surface of Earth
What is basalt? Basalt is a volcanic stone - it shoots out of volcanoes as a liquid and then solidifies. It's very hard, and ancient people used it for carving states, for grindstones, and for paving streets.
Today, Basalt is known as a vacation mecca for families and sports enthusiasts. Located between Glenwood Springs and Aspen, world-class skiing and cultural opportunities are only minutes away.Amid the myriad of activities, Basalt still preserves it original, quaint charm.
Basalt Basalt is a mafic extrusive rock, is the most widespread of all igneous rocks, and comprises more than 90% of all volcanic rocks. Because of its relatively low silica content, basalt lava has a comparatively low viscosity, and forms thin flows that can travel long distances.

May 29, 2013· Formation of Columnar Basalt is quickly described in this 2 Minute Geology episode. Columnar Basalt is the result of cooling and cracking of an unusually thick basaltic lava flow. Columns are ...
Basalt is primarily formed by the extrusion of lava flows onto the surface of the earth during a volcanic eruption. The intrusion of a narrow sill or igneous dike below the crust also results in the formation of basalt. Basalt is a type of igneous rock that is typically dark in coloration with a ...
The Basalt Fiber History From a volcanic lava to an advanced composite. From Lava to Rock. Basalt is a type of igneous rock formed by the rapid cooling of lava at the surface of a planet.
Basalt. Basalt is a mafic (dark) igneous, extrusive volcanic rock. As such, basalt may be vesicular (containing small cavities) and brecciated (having angular fragments). It …
Basalt is fine grained so the individual minerals are not visible, but they include pyroxene, plagioclase feldspar and olivine. These minerals are visible in the coarse-grained, plutonic version of basalt …
The trick is to heat the basalt back up again so it can melt and give the iron another shot at the core. It wants to be there, and heat is the key which unlocks the door. As it turns out, most of the ocean floor is basalt, and most of the continents are granite. Basaltic crust is dark and thin and heavy, while granite is light and accumulates ...

Basalt is the dark, heavy volcanic rock that makes up most of the world's oceanic crust. Some of it erupts on land, too, but to a first approximation basalt is an oceanic rock. Compared to the familiar granite of the continents, basalt ("ba-SALT") is darker, denser and finer grained.
Basalt Basalt is a dark heavy lava that is very hot and fluid when it erupts. It it erupts on the continents it can flow many kilometers before it cools in thin layers. It it erupts on the continents it can flow many kilometers before it cools in thin layers.
Basalt is an igneous rock that forms from the relatively rapid solidification of basaltic lavas; that is, those magmas that are relatively high in iron and magnesium, and low in silica and aluminum. These features give basalt its dark color and higher relative density when compared to silicate igneous rocks.
Basalt is a common extrusive igneous rock formed by the rapid cooling of basaltic lava exposed at or very near the surface of Earth
Basalt is one of the most common rock types in the world. Basalt is the rock most typical of large igneous provinces. The largest occurrences of basalt are in the ocean floor that is almost completely made up by basalt. Above sea level basalt is common in hotspot islands and around volcanic arcs, specially those on thin crust.
It is a kind of igneous rock formed by the cooling of a certain type of molten lava. The lava cools and then hardens into a fine-grained crystalline rock (see lava and magma). The word basalt is believed to have come from an ancient Ethiopian word, basal, meaning "a rock from which iron can be derived."
Basalt is a very common dark-colored volcanic rock composed of calcic plagioclase (usually labradorite), clinopyroxene and iron ore (titaniferous magnetite).Basalt may also contain olivine, quartz, hornblende, nepheline, orthopyroxene, etc. Basalt is a volcanic equivalent of gabbro.
basalt - the commonest type of solidified lava; a dense dark grey fine-grained igneous rock that is composed chiefly of plagioclase feldspar and pyroxene pyroxene - any of a group of crystalline silicate mineral common in igneous and metamorphic rocks
Basalt is a fine grained volcanic igneous rock formed of plagioclase and pyroxene minerals. It is most commonly formed by lava flow and in sills and dykes.Basalt is similar to gabbro in composition but the difference lies in the grain size of the two rocks.
Basalt is a good building material and can be used for making gravel and block rubble, as well as for facing buildings. Basalt is durable and polishes well. For this reason, it has long been used for sculpture (ancient Egypt, Assyria, late Rome, Byzantium, and contemporary Armenia).
Basalt is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes, so it's one kind of igneous rock. When the lava cools quickly, it turns into basalt. Usually basalt is black or gray. Basalt is a mixture of feldspar and pyroxene, a rock made mainly of silica and oxygen. Pyroxene […]

Basalt is a typically dark-colored, extrusive igneous rock, and igneous means that it formed from rapidly-cooled lava on the earth's surface. Remember that extrusive means it hardens at the ...
What is Basalt? Basalt is a dark-colored, fine-grained, igneous rock composed mainly of plagioclase and pyroxene minerals. 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.

Basalt makes up most of the ocean floor and is the most common type of lava. It sometimes cools into characteristic hexagonal columns, as in the Giant's Causeway in Anterim, Northern Island. It is the fine-grained equivalent of gabbro.
