Read MoreBasalt is an extrusive igneous or volcanic rock that has a low silica content, dark in color, and very rich in iron and magnesium. A basalt dark in color can be called the dark basalt. We find its applications in textile industries, fire protection. From these places, we get a clear idea that understanding basalt use is really important for us.
Read More· How Is Basalt Formed? 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 fine-grained texture. It is ...
Read MoreDefinition of Basalt. With a name derived from the Latin for ''very hard stone'', basalt is indeed a very hard, black igneous rock found all over Earth and our solar system. It can be found not only ...
Read MorePillow basalt is a type of Basaltin whichlava erupts underwater or flows into the sea. Contact with the water quenches the surface and the lava forms a distinctive pillow shape, through which the hot lava breaks to form another pillow. This "pillow" texture is very common in underwater basaltic flows and is diagnostic of an underwater eruption environment when found in ancient rocks. Pillows ...
Read More· Basaltic magma contains between 45 and 55 percent silicon dioxide and is high in magnesium, iron and calcium, while granitic magma contains between 65 and 75 percent silicon dioxide and only small amounts of those minerals. Granitic magma has high levels of potassium and sodium, while basaltic magma has very low levels of these minerals.

Read MoreIntrusive, or plutonic, igneous rocks form when magma cools slowly below the Earth''s surface. Granite and gabbro are examples of phaneritic igneous rocks ne grained rocks, where the individual grains are too small to see, are called aphanitic.Basalt is an example.
Read More· Basalt is volcanic, or extrusive, forming at the surface, while granite is plutonic, or intrusive, forming beneath the surface. Basalt is mafic while granite is felsic. Basalt is common on both Earth and other Solar System bodies such as the Moon and Mars while granite is only common on Earth and rare elsewhere in the Solar System.

Read More· Basalt is a dark-colored, fine-grained, igneous rock composed mainly of plagioclase and pyroxene minerals 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. ...
Read More· According to About the density of granite ranges from 2.6-2.7 g/cm 3 and basalt is 2.8-3.0 g/cm 3. Since gabbro and basalt are made of the same minerals, their densities are similar. Gabbro''s density ranges from 2.7-3.3 g/cm 3. The day after the lab is a good time to question the students about the significance of rock densities.
Read More· Basalt is an extrusive igneous rock; extrusive rocks are those that form from lava coming out of volcanoes. Cooling of intrusive rocks takes much longer than extrusive rocks. The basalt rocks split along columnar planes.

Read MoreAnd the seafloor basalt ends up in pretty much the same position as does the VW - under the truck (or continent, as the case may be). This may seem like a drag for the basalt, but remember that it isn''t all that happy on the surface anyway, and this gives it the heat it needs to re-melt and try to complete the differentiation process which was so rudely interrupted at the spreading ridge.

Read MorePillow lavas are lavas that contain characteristic pillow-shaped structures that are attributed to the extrusion of the lava underwater, or subaqueous extrusion. Pillow lavas in volcanic rock are characterized by thick sequences of discontinuous pillow-shaped masses, commonly up to one meter in diameter. They form the upper part of Layer 2 of ...
Read More· Pillow basalt is a volcanic igneous rock that forms when lava of basaltic compositionis erupted underwater. The rapid cooling of the lava by cold water on all sides forms the pillow-shaped bodies, which can then break open and extrude more of the hot lava from inside. The rapid cooling also creates pillows that are composed of volcanic glass on ...
