Does obsidian rock contain few or no mineral grains?
Obsidian is a type of volcanic glass that lacks a crystalline structure, so it does not contain mineral grains. It forms from quickly cooling lava rich in silica, resulting in a smooth, glassy texture without distinct mineral crystals.
Is obsidian malleable?
No. Obsidian is brittle.
What is a type of obsidian?
One type of obsidian is snowflake obsidian, which is black with white mineral inclusions that resemble snowflakes.
Smooth glassy rock that is formed when lava cools?
Obsidian
How is obsidian dependent to minerals?
how is obsidian dependent on minerals
Why is the texture of obsidian is best contain few or no minerals grains?
Obsidian cools so quickly the mineral grains do not have time to form.
Does obsidian have poison in it?
Yes, obsidian has a toxic poison that can make you very sick and/or kill you, if you get it in your body and don't go to the hospital. If you get obsidian in your body, I suggest you call 911. And don't play with it either.
Does obsidian bubble when doing a acid test?
Obsidian does not bubble when tested with acid. Obsidian is a volcanic glass with a smooth and shiny texture that is not reactive to acid. Its lack of bubbles distinguishes it from minerals that contain carbonate compounds, which may react with acid by producing bubbles.
Does obsidian rock contain few or no mineral grains?
Obsidian is a type of volcanic glass that lacks a crystalline structure, so it does not contain mineral grains. It forms from quickly cooling lava rich in silica, resulting in a smooth, glassy texture without distinct mineral crystals.
Is obsidian rock organic or chemical?
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.
Is pumice and obsidian forms of volcanic gas?
Partially correct. Pumice forms from rapidly cooling lava containing volatiles (water and gas) and obsidian forms from rapidly cooling lava that doesn't contain volatiles. Bubbles from volatiles are frozen in place and cannot escape before the lava hardens forming pumice. Obsidian and pumice are sometimes found together although obsidian itself is relatively rare.
Why does obsidian contain few or no grains?
The material that would normally form mineral crystals does not have time to form a crystalline structure because of very rapid cooling after volcanically erupting into the air or onto the surface. Obsidian is a volcanic glass.
Is obsidian malleable?
No. Obsidian is brittle.
What is a type of obsidian?
One type of obsidian is snowflake obsidian, which is black with white mineral inclusions that resemble snowflakes.
Smooth glassy rock that is formed when lava cools?
Obsidian
What are the minerals in obsidian?
Obsidian is, itself, a mineral.
Is obsidian glass?
Obsidian is a natural glass.
