Does obsidian have any minerals?
Obsidian consists of about 70 percent or more non-crystallized silica (silicon dioxide). Because obsidian is not comprised of mineral crystals, technically obsidian is not a true “rock.” It is really a congealed liquid with minor amounts of microscopic mineral crystals and rock impurities.
What is the composition of snowflake obsidian?
Most black obsidians contain nanoinclusions of magnetite, an iron oxide. Very few samples of obsidian are nearly colorless. In some stones, the inclusion of small, white, radially clustered crystals (spherulites) of the mineral cristobalite in the black glass produce a blotchy or snowflake pattern (snowflake obsidian).
What type of rock is snowflake obsidian?
igneous rock
Snowflake Obsidian is formed when the felsic lava from a volcano rapidly cools down with very minimum crystal growth. It’s basically a volcanic glass that formed as an igneous rock. Obsidian’s high silica content makes the lava it forms from highly viscous, or thick.
Is snowflake obsidian rare or common?
Protogenic silica minerals crystallizing in obsidian may be white and resemble snowflakes, hence the term snowflake obsidian. Black; gray, banded with brown streaks. Green, blue, and reddish stones (transparent) are very rare.
Why is obsidian not a crystal?
Obsidian does not have crystals because it forms from felsic lava, which is lava that is high in silica.
What is the difference between obsidian and snowflake obsidian?
The only difference between snowflake obsidian and black obsidian pieces are the “snowflakes” that you see on its surface. The presence of such snowflakes marks the slow process of transformation of obsidian from volcanic glass into an actual rock.
