Vesicular texture -- basalt scoria: This is an extrusive igneous rock that chilled very quickly, so that the bubbles (vesicles) formed by escaping gas were preserved. Rock types that display a vesicular texture include pumice and scoria. Meteorites derived from Vesta also show a vesicular texture believed to have formed deep within the asteroid (McCoy et al. One example of each type is provided below. Vesicular texture is a volcanic rock texture characterized by a rock being pitted with many cavities (known as vesicles) at its surface and inside. Basalts are formed by the rapid cooling of basaltic lava, equivalent to gabbro-norite magma, from interior of the crust and exposed at or very close to the surface of Earth. Basalt is a mafic extrusive rock, is the most widespread of all igneous rocks, and comprises more than 90% of all volcanic rocks. Vesicular basalt arising from extruded magma in which gasses have expanded to produce cavities in the rock. The basalt rebar consists of 80% of basalt fiber that offers better mechanical property to the reinforced concrete.

The extrusive rocks scoria and pumice have a vesicular, bubble-like, texture due to the presence of vapor bubbles trapped in the magma. . . They are resistant to water penetration and impact and tolerate industrial environments well. The matrix is fine grained, often porphyritic. Most of Earth's surface is basalt lava, but basalt makes up only a small fraction of continents. If the cavities are infilled with minerals, vesicular basalt becomes an amygdaloidal basalt.

Texture: aphanitic and vesicular (contains abundant large gas cavities) Composition: intermediate (andesitic) to mafic (basaltic) Color: black or dark brown. When the magma finally reaches the surface as lava and cools, the rock solidifies around the gas bubbles and traps them inside, preserving them as holes filled with gas called vesicles. Amygdaloids are simply vesicles that have been filled in with a secondary mineral long after the flow cooled. There are many types of basalt with different proportions of elements. Once outside, the hot lava cools very quickly as it comes into contact with either the air or ocean water. When the magma finally reaches the surface as lava and cools, the rock solidifies around the gas bubbles and traps them inside, preserving them as holes filled with gas called vesicles. When igneous rocks contain two distinct grain sizes, the texture is porphyritic, and the finer crystals are called the groundmass. No need to register, buy now! The basalt flows belong to the Arabian Harrat volcanism. It may be compact or vesicular (porous) because of gas bubbles contained in the lava while it was cooling. This causes the magma to foam up, and the resulting rock to be riddled with hole-like structures called vesicles. Basalt with a vesicular texture is called vesicular basalt, when the bulk of the rock is mostly solid; when the vesicles are over 1/2 the volume of a specimen, it is called scoria.
