What family is obsidian in?
Obsidian is part of the Granite family of igneous rocks.
What rock is a obsidian and basalt?
Obsidian is a volcanic glass formed from rapidly cooling lava, while basalt is a fine-grained, dark-colored igneous rock formed from the solidification of lava flows. Both rocks are commonly found in volcanic areas and have high silica content.
Can obsidian turn into diamond?
Obsidian and diamond are formed under different conditions and from different materials, so obsidian cannot naturally turn into diamond. Obsidian is a volcanic glass formed from rapidly cooled lava, while diamonds are formed deep within the Earth's mantle under high pressure and temperature.
What has the highest concentration of silica?
The highest concentration of silica is typically found in certain types of volcanic rocks, particularly rhyolite and obsidian, which can contain up to 80% silica. Additionally, some sedimentary rocks, such as sandstone and chert, also have high silica content. Silica is a key component of quartz, which is one of the most abundant minerals in the Earth's crust.
What minerals are obsidian made up of?
There are no minerals in obsidian. Obsidian is a silica-rich volcanic glass, which cools too quickly to produce crystals. A mineral must have an ordered atomic structure and a distinct chemical composition. The size of a crystal depends on cooling rate of the magma: slower cooling correlates to larger crystal size. If a magma cools too quickly, the elements don't have time to organize themselves into crystals, and will "freeze" in place as a glass. Obsidian often has a chemical composition similar to a granite, meaning that the ratios of different elements and oxides would be the same. The major difference between these two rocks is cooling rate--granite cools slowly, deep underground, while obsidian cools quickly on the surface.
Why do obsidian rocks look dark?
because an obsidian rock has low silica
What is possible origin of obsidian?
Obsidian is volcanic glass, derived from the quick cooling of high silica lava.
What the rock is obsidian made of?
Obsidian is a volcanic glass, so the main component is silica. It is 70-75% SiO2, plus MgO, Fe3O4. Mainly from molten granite, carbonated basalt and quartz for shininess.

Is obsidian a diamond?
No, obsidian and diamond are two different materials. Obsidian is a naturally occurring volcanic glass, while diamond is a crystalline form of carbon. They differ in composition, appearance, and properties.
What family is obsidian in?
Obsidian is part of the Granite family of igneous rocks.
How is obsidian glass made?
Obsidian, or "volcanic glass," is made when molten rock comes out of a volcano and cools so quickly that no crystalline structure has time to form. This makes obsidian an extrusive igneous rock. The cooling occurs right at the surface.

What is glass and how it is made?
Glass is silica dioxide. It is made by melting silica sand.
