Definition
Obsidian is a naturally occurring volcanic glass formed as an extrusive igneous rock. It is produced when felsic lava extruded from a volcano cools rapidly with minimum crystal growth
Enderbite rock is an igneous rock which belongs to the Charnockite rock series

Formation
When the lava is released from volcano, it undergoes a very rapid cooling which freezes the mechanisms of crystallization. The result is a volcanic glass with a uniform smooth texture.
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.
