- Basalt is the most common volcanic rock: It is formed as the volcanic magma erupts onto the surface or even in the water and undergoes a rapid cooling process. It has varying shades of grey to black.The fast cooling process makes the creation of the minerals almost invisible, making it a fine-grained substance. Modern Use. Today, basalt is used to a lot of things. Most common use of. is as aggregates. Basalts that are crushed are used for construction purposes, like asphalt paving, concrete aggregate and rock filtering agents. Basalts are added as aggregates to increase strength to concrete.

- While it isn't as widely used as limestone or granite, basalt does have some uses. It can be used for structural building materials, like bricks or foundations, and sculptures. Certain shapes of basalt can be used for cobblestones and exterior road or landscape materials.

- Shield Volcanoes. Because mafic lava is low viscosity, when it erupts from a volcano it flows downslope away from the vent, gradually cooling and crystallizing. Because of the relative ease of flow, basaltic volcanoes are broad, with gentle slopes. They don't have the stereotypical steep volcanic cone shape.hield Volcanoes.

Coastal Erosion Features 1 The area under attack is eroded using the major processes of coastal erosion. 2  Points of weakness, such as faults and joints are attacked most, and eventually a wave-cut notch is gouged out. 3  The rock above overhangs the notch, and as it is cut deeper into the rock, gravity causes the overhanging rock to collapse. Cliffs are formed when destructive waves attack the bottom of the rock face between high and low water mark. 2  The area under attack is eroded using the major processes of coastal erosion. 3  Points of weakness, such as faults and joints are attacked most, and eventually a wave-cut notch is gouged out.

Basalt The third basalt-forming environment is a continental environment where a mantle plume or hotspot delivers enormous amounts of basaltic lava through the continental crust and up to Earth's surface. These eruptions can be from either vents or fissures.They have produced the largest basalt flows on the continents.t 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 underlies more of Earth's surface than any other rock type. Most areas within Earth's ocean basins are underlain by basalt.

Basalt Basalt is a major rock type that occurs in virtually every tectonic setting. Basalt is clearly the most common volcanic rock on Earth and basaltic rocks (including gabbro, diabase and their metamorphosed equivalents) are the most common rocks in the crust2. Basalt is also common on the Moon and other rocky planets of the Solar System.

- Basalt 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. It is also found as intrusive dikes and sills.

Mesa Variations in the ability of different types of rock to resist weathering and erosion cause the weaker types of rocks to be eroded away, leaving the more resistant types of rocks topographically higher than their surroundings. This process is called differential erosion. The most resistant rock types include sandstone, conglomerate, quartzite, basalt, chert, limestone, lava flows and sills. Lava flows and sills, in particular, are very resistant to weathering and erosion, and often form the flat top, or caprock, of a mesa.

Weathering and erosion Once the rock has been weakened and broken up by weathering it is ready for erosion. Erosion happens when rocks and sediments are picked up and moved to another place by ice, water, wind or gravity. Mechanical weathering physically breaks up rock. One example is called frost action or frost shattering. Water gets into cracks and joints in bedrock. When the water freezes it expands and the cracks are opened a little wider. Over time pieces of rock can split off a rock face and big boulders are broken into smaller rocks and gravel. This process can also break up bricks on buildings.

About Basalt Midocean-Ridge Basalts. Basalt is a type of lava that the rocks of the mantle make when they start to melt. If you think of basalt as mantle juice, the way we talk about extracting oil from olives, then basalt is the first pressing of mantle material. The big difference is that whereas olives yield oil when put under pressure, midocean-ridge basalt forms when pressure on the mantle is released.

- Lava channels can develop in both pahoehoe and a'a basalt. Once established, lava channels will often develop lava levees along their lengths. In pahoehoe flows, natural levees will be constructed as the channel periodically overflows, thus allowing the lava to congeal and cool along the banks of the channel. In a'a flows, levee buildup can also occur by the bulldozing effect of the moving lava, which will push a'a blocks onto the lava banks. Although lava channels may initially be restricted to a topographic valley, as levees build up over time, they may eventually rise above the surrounding ground surface.

Basalt Most of Earth's basalt is produced at divergent plate boundaries on the mid-ocean ridge system (see map). Here convection currents deliver hot rock from deep in the mantle. This hot rock melts as the divergent boundary pulls apart, and the molten rock erupts onto the sea floor.

- Lava is the form of molten rock. But, when it … cools in air, it is more of a Basalt. When it cools well beneath the surface, under pressure from above, it takes the form of a Granite. However, we do use, for landscaping purposes, a form of it that has been cooled in water and is very porous (open-celled).

Gabbro However, only a thin surface veneer of oceanic crust is basalt. The deeper rocks of the oceanic crust are generally coarser-grained gabbro. Basalt occurs at the surface of the crust because the rocks there have cooled quickly. At greater depth the cooling rate is slower, and large crystals have time to develop. (See illustration.)

Basalt 1 Some basalts are quite glassy (tachylytes), and many are very fine-grained and compact. It is more usual, however, for them to exhibit porphyritic structure, with larger crystals (phenocrysts) of olivine, augite, or feldspar in a finely crystalline matrix (groundmass).

Igneous Rocks: How Are They Formed? Basalt is a common form of extrusive igneous rock and forms lava flows, lava sheets and lava plateaus. Extrusive igneous rocks include andesite, basalt, obsidian, pumice, rhyolite, scoria, and tuff. Because the minerals are mostly fine-grained, it is much more difficult to distinguish between the different types of extrusive igneous rocks than between different types of intrusive igneous rocks.

Runoff and Erosion Like running water on the surface, groundwater affects the shape of the land. Groundwater can cause erosion through a process of chemical weathering. When water sinks into the ground, it combines with carbon dioxide to form a weak acid, called carbonic acid.Carbonic acid can break down limestone. Groundwater containing carbonic acid flows into any cracks in the limestone.ike running water on the surface, groundwater affects the shape of the land.

Ask GeoMan... Basalt and granite actually have quite a bit in common. Both are igneous rocks, which means that they cooled from a magma (the earth gets very hot just below the surface, and there is lots of liquid rock available).Both are made up of minerals from the silicate group, so both have large amounts of silicon and oxygen.ranite is intrusive, which means that the magma was trapped deep in the crust, and probably took a very long time to cool down enough to crystallize into solid rock. This allows the minerals which form plenty of time to grow, and results in a coarse-textured rock in which individual mineral grains are easily visible.

What is basalt? Basalt (pronounced /bəˈsɔːlt/, /ˈbæsɒlt/ or /ˈbæsɔːlt/) is a common extrusive igneous (volcanic) rock formed from the rapid cooling of basaltic lava exposed at or very near the surface of a planet or moon. Flood basalt describes the formation in a series of lava basalt flows.
