Obsidian and granite are both igneous rocks. Obsidian is of extrusive origin (which means the magma cooled quickly) and has a glassy texture. Granite is of intrusive origin (which means the magma cooled slowly) and is phaneritic, or coarse grained.y

How are granite and obsidian are different?

Granite is a rock, whereas obsidian is a type of glass formed by cooling lava.


Can Obsidian turn into Granite?

No, Obsidian and Granite are two different types of rocks with distinct properties. Obsidian is a volcanic glass formed from rapidly cooling lava, while Granite is an igneous rock made up of various minerals like quartz and feldspar. They have different mineral compositions and formation processes, so Obsidian cannot turn into Granite.

How does granite form into Obsidian?

Granite does not directly transform into obsidian. Obsidian is formed when lava cools very quickly, without giving crystals a chance to form. Granite, on the other hand, forms deep beneath the Earth's surface through the slow cooling and solidification of magma. So, while both are igneous rocks, they form under different conditions.

What volcano does obsidian come from?

Obsidian is a felsic glass. At depth, it will crystallize to form granite. On the other hand it turns into perlite on reacting with water. At high grade it recrystallizes to form felsic glass.

Which rock has large mineral grains granite obsidian basalt or pumice?

Granite has large mineral grains compared to obsidian, basalt, and pumice. Granite is an intrusive igneous rock that forms deep within the Earth's crust, allowing for the growth of large mineral crystals due to slow cooling. Obsidian, basalt, and pumice are extrusive igneous rocks that cool quickly at the Earth's surface, resulting in smaller mineral grains or a glassy texture.
