What is Rutile?
Rutile is a titanium oxide mineral that is most commonly found in granites, pegmatites, and metamorphic rocks. It is also found in sands derived from the weathering of these rocks. Rutile also forms as slender crystals within quartz and micas. It is a common mineral in the alluvial sands that are dredged for magnetite and ilmenite.
