    WebObsidian (/ ə b ˈ s ɪ d i. ən, ɒ b-/ əb-SID-ee-ən ob-) is a naturally occurring volcanic glass formed when lava extruded from a volcano cools rapidly with minimal crystal growth. It is an igneous rock. Obsidian is produced from felsic lava, rich in the lighter elements such as silicon, oxygen, aluminium, sodium, and potassium.

    WebObsidian is an igneous rock that forms when molten rock material cools so rapidly that atoms are unable to arrange themselves into a crystalline structure. It is an amorphous material known as a " mineraloid ." The result is a volcanic glass with a smooth uniform texture that breaks with a conchoidal fracture (see photo).

    WebJun 23, 2023 · Obsidian is a hard, brittle, natural volcanic glass or mineraloid with a conchoidal fracture. It is not a mineral or crystal. However, it is often considered a volcanic or an extrusive igneous rock. Usually, obsidian is a rhyolite glass formed from rapid quenching viscous, silica-rich lava or magma.

If it was an igneous rock that formed from magma underground and did not erupt, it would have been called an "intrusive" rock.

    WebObsidian. Obsidian is a massive volcanic glass. The term ‘massive’ has several (although related) meanings in geology but here it means that the rock (obsidian is a rock type, not a mineral) is homogenous. It lacks layering, cleavage, foliation, phenocrysts, etc. It is just a piece of volcanic glass without further conditions.
