It is an igneous rock. Obsidian is produced from felsic lava, rich in the lighter elements such as silicon, oxygen, aluminium, sodium, and potassium. It is commonly found within the margins of rhyolitic lava flows known as obsidian flows. These flows have a high content of silica, giving them a high viscosity.

Why is rhyolite so high in silica?
Rhyolite (/ˈraɪ.əˌlaɪt/ RY-ə-lyte) is the most silica-rich of volcanic rocks. Magma with the composition of rhyolite is extremely viscous, due to its high silica content. This favors explosive eruptions over effusive eruptions, so rhyolitic magma is more often erupted as pyroclastic rock than as lava flows.
Is obsidian rare?
Obsidian is relatively unstable from a geologic perspective. It is rare to find obsidian older than about 20 million years, which is very youthful in comparison to most continental rocks that form the Earth’s crust.

How is rhyolitic lava formed?
Rhyolite is a volcanic rock. It is fine-grained because it forms by the rapid cooling of magma, usually when it erupts onto the Earth’s surface. When rhyolite erupts quietly it forms lava flows. If it erupts explosively it often forms pumice.
Is obsidian really strong?
Strong almost beyond compare and able to stand huge blasts, glossy, black obsidian is forged in the very fires of the earth. That’s because obsidian is glass, and rather than being super tough, it’s brittle, shattering easily. But this lends obsidian its greatest strength, something early humans knew all about.
Is hardened lava called obsidian?
It’s called obsidian, and it’s a naturally occurring volcanic glass formed when felsic lava flows from a volcano and then cools without crystal growth. In a regular eruption, lava pours out of a volcano out onto the surface travels a distance downhill, and then hardens.
