Ask GeoMan... Which country on earth has 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. Because of this density difference, basalt is usually found on the seafloor. Therefore, since it's what makes the seafloor, MOST basalt is not part of ANY country. However, most of the continents will have some basalt exposed at the surface.

Where is granite found? Granite forms deep underground from slow cooling magma, therefore, granite can be found as the base rock of most continents and as plutons beneath the surface. In areas where … overlying rock and sediment have eroded away the material above these features, granite is exposed at the surface.

Talk:Basalt By definition, basalt is an aphanitic igneous rock with less than 20% quartz and less than 10% feldspathoid by volume, and where at least 65% of the feldspar is in the form of plagioclase.Basalt features a glassy matrix interspersed with minerals.asalt which erupts under open air (that is, subaerially) forms three distinct types of lava or volcanic deposits: scoria; ash or cinder (breccia); and lava flows. Basalt in the tops of subaerial lava flows and cinder cones will often be highly vesiculated, imparting a lightweight frothy texture to the rock.

- Basalt is a type of volcanic igneous rock that forms outside of the earth and is used for different purposes in construction. Discover how basalt is used as a major component of asphalt for roads with help from a science tutor and field biologist in this free video on basalt and chemistry.o, basalt is a type of volcanic rock. It's also an extrusive volcanic rock which simply means that it formed outside of the earth. So, it cools, it gets ejected or it goes out into the surface of the earth and cools in air.

- It is the most common volcanic rock type on Earth, being a key component of oceanic crust as well as the principal volcanic rock in many mid-oceanic islands, including Iceland, Réunion and the islands of Hawaii. Basalt commonly features a very fine-grained or glassy matrix interspersed with visible mineral grains.

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. It has a composition similar to gabbro.he 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.

Obsidian Obsidian can be found in locations which have experienced rhyolitic eruptions. It can be found in Argentina, Armenia, Azerbaijan, Australia, Canada, Chile, Georgia, Greece, El Salvador, Guatemala, Iceland, Italy, Japan, Kenya, Mexico, New Zealand, Papua New Guinea, Peru, Scotland, Turkey and the United States.t is produced when felsic lava extruded from a volcano cools rapidly with minimum crystal growth. Obsidian is commonly found within the margins of rhyolitic lava flows known as obsidian flows, where the chemical composition (high silica content) induces a high viscosity and polymerization degree of the lava.

- They are both formed by the crystallisation of magma. Basalt is formed when basic (i.e. high iron and magnesium, low silica) magma freezes above ground as a lava flow, … resulting in the very fine crystals. Granite is the crystallised form of more felsic (silica-rich) magma, which has crystallised at depth within the Earth, resulting in a large crystal size.

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. Many moon rocks brought back by Apollo astronauts are of basaltic composition. Basalt is the volcanic equivalent of gabbro.
