Obsidian is an extrusive igneous rock because it is formed from the rapid cooling of magma after eruption ontoEarth's surface. The rapid cooling of lava results in a fine-grained texture, or in this case (with obsidian), a glassy texture, where cooling takes place so rapidly that mineral crystals do not have time to form. Rock that is formed from slow cooling magma beneath the surface is intrusive igneous rock, and exhibits visible mineral crystals.
Obsidian is an extrusive igneous rock.
Golconda Fort is primarily made of a form of granitic rock known as "grey granite." This type of rock is known for its durability and strength, which made it a popular choice for building forts and structures in the region.
Granite is a coarse grained igneous rock without Pyroxene.
Obsidian is an igneous rock.So the answer is YES.
Obsidian is a volcanic glass which forms when a high silica melt solidifies quickly after eruption. Organic and chemical are terms used to classify sedimentary rock. Obsidian is an igneous rock type.

No. Obsidian is volcanic glass. Glass is amorphous and thus noncrystalline.
Volcanic rock.
No. Obsidian is just one of many types of volcanic rock.
Obsidian is an extrusive felsic igneous rock.
Obsidian is an igneous rock that forms from lava cooling extremely quickly, preventing the formation of crystals. It is often referred to as a natural glass due to its lack of crystal structure.
The common name for obsidian rock is volcanic glass.
