• Vesicular texture - Wikipedia

    en.wikipedia.org/wiki/Vesicular_texture Vesicular texture is a volcanic rock texture characterized by a rock being pitted with many cavities (known as vesicles) at its surface and inside. This texture is common in aphanitic, or glassy, igneous rocks that have come to the surface of the earth, a process known as extrusion. As magma rises to the surface the pressure on it decreases.

  • IgnRx Study Guide - Vesicular Classification

    igg.georockme.com/texture/vesicular-classification When volcanoes erupt at the earth's surface, pressure is rapidly released and dissolved gas forms bubbles of vapor that may move through liquid lava. Rapid loss of heat leads to rapid cooling and solidification of the lava into rock, trapping the gas bubbles and forming vesicles - holes or cavities. The density of vesicles may vary greatly, with some rock resembling a foam (or perhaps like a loaf of fluffy white bread) that is mostly vesicles, and other rocks more dense with a smattering of ...

    www.brooklyncollegegeology.com/fourth/textures.htm Vesicular texture is a volcanic rock texture characterised by, or containing, many vesicles. The texture is often found in extrusive aphanitic, or glassy, igneous rock. The vesicles are small cavities formed by the expansion of bubbles of gas or steam during the solidification of the rock.

So, a rock that looks like Swiss cheese has a vesicular texture. Vesicles range in shape from spherical to elongated and in size from ~1mm to more than 1 cm. Basalts are most commonly vesicular.

    geol105.sitehost.iu.edu/images/gaia_chapter_5/igneous_rock_textures.htm F) VESICULAR TEXTURE (Open spaces, bubbles) If magma contains dissolved gases, these will tend to bubble out when the magma comes to the surface (just like CO 2 bubbles out of a bottle of Seltzer). Because cooling is rapid, not all the gas may escape from the lava flow and bubbles (vesicles) are preserved.
