Classifying Igneous Rock
... For a rock to be classified as igneous, it must have been melted at some time and then hardened to become solid again. When melted rock material (magma or lava) cools and hardens, it may form crystals, depending on how fast it. How fast the rock material cools depends on where it cools. If melted ro ...

Clastic rock
Clastic rocks are composed of fragments, or clasts, of pre-existing minerals and rock. A clast is a fragment of geological detritus, chunks and smaller grains of rock broken off other rocks by physical weathering. Geologists use the term clastic with reference to sedimentary rocks as well as to particles in sediment transport whether in suspension or as bed load, and in sediment deposits.
