The texture of extrusive rocks is characterized by fine-grained crystals indistinguishable to the human eye, described as aphantic. David Mackenzie Movies, [2] Pumice is a light-weight, glass with a vesicular texture that differs from scoria in its silicic composition and therefore floats. It is a volcanic (extrusive) igneous rock - the outward texture is coarse, but not because of the composition (which is what the ‘textural definition’ of intrusive and extrusive igneous rocks means) but because of the nature of the eruption of the lava. Scoria is the primary rock for cinder cone volcanoes. Tristram Shandy Pdf, Igneous rocks are formed when molten magma or lava cools and solidifies. The extrusive rocks scoria and pumice have a vesicular, bubble-like, texture due to the presence of vapor bubbles trapped in the magma. The slower the cooling process, the longer the crystals have time to form. [6], Lava domes are formed by high viscosity lava that piles up, forming a dome shape. Some extrusive rocks cool so quickly that they do not form any grains. Scoria is heavier than pumice and does not float on water. Although Basalt almost always forms extrusive igneous rock on lava flows, it may sometimes take the form of small intrusive rock bodies like the igneous dike and a thin sill.

Basalt is rich in iron and magnesium and is mainly composed of olivine, pyroxene, and plagioclase. If the magma contains abundant volatile components which are released as free gas, then it may cool with large or small vesicles (bubble-shaped cavities) such as in pumice, scoria, or vesicular basalt.
