2020-4-17Vesicular texture is a volcanic rock texture characteried 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. When this happens gasses dissolved in the magma are
2015-1-14VESICULAR BASALT. Vesicular Basalt is similar to basalt except that it has a few small holes in it. It has fewer holes than a scoria. The holes form as the drop in pressure that a magma experiences as it flows from underground to the Earths surface

Basalt. Basalt is a mafic dark igneous extrusive volcanic rock. As such basalt may be vesicular containing small cavities and brecciated having angular fragments. It
Vesicular basalt has empty bubble-shaped holes but were once filled with gas. These holes called vesicles form during the extrusion of magma to the surface
Scoria and Basalt belong to Igneous Rocks.Texture of Scoria is Vesicular whereas that of Basalt is Glassy Massive Porphyritic Scoriaceous Vesicular. Scoria appears Glassy and Vesicular and Basalt appears Dull and Soft. The luster of Scoria is subvitreous to dull while that of Basalt is not available
