Vesicular basalt

Virtual Museum ID: 19-DE03

Specimen Summary


Vesicular Basalt is a dark igneous rock that contains small vesicles that was formed by the expansion of a bubble of gas that was trapped within the lava.

Opal is a mineraloid composed of amorphous silica. It is not considered a true mineral as it lacks an ordered atomic arrangement. This is due to the presence of water, differentiating it from crystalline silica (quartz). The internal structure of opal causes it to diffract light, producing pearly iridescence.
