1.1 Definition
Rhyolite is a fine-grained igneous rock which is rich in silica
Marble is a non-foliated metamorphic rock which is composed of recrystallized carbonate which is formed when limestone is exposed to high temperatures and pressures over a long time

5 Formation
5.1 Formation
Rhyolite is a felsic extrusive rock and due to its high silica content, rhyolite lava is very viscous and is volcanic equivalent of granite.
Marble is a metamorphic rock produced from limestone in the earth crust. It is formed by the metamorphism of limestone.
