Volcanic glass

Obsidian

Obsidian is produced when felsic lava extruded from a volcano cools rapidly with minimal crystal growth.  It is commonly found within the margins of rhyolitic lava flows known as obsidian flows.

Conglomerate

Sedimentary

Conglomerates form by the consolidation and lithification of gravel. They can be found in sedimentary rock sequences of all ages but probably make up less than 1 percent by weight of all sedimentary rocks.
