Rhomb Porphyry

Generally rough to touch, Is one of the oldest rock, Surfaces are often shiny

Absent

Porphyry is formed in two stages: the magma cools slowly deep within the crust or the magma is cools rapidly as it erupts from a volcano, creating small grains that are usually invisible to naked eye.
