Pyroclastic rock Wikipedia

Pyroclastic rocks derived from the Greek πῦρ meaning fire and κλαστός meaning broken are clastic rocks composed of rock fragments produced and ejected by explosive volcanic eruptions The individual rock fragments are known as pyroclastsPyroclastic rocks are a type of volcaniclastic deposit which are deposits made predominantly of volcanic particl
