Zircon & allied mineral

ZIRCON is the chief mineral of zirconium, a versatile metal. The zircon is a common accessory mineral of igneous rocks, like syenite, granite and diorite. Economic deposits are, however, concentrated along the beach sands and found in association with ilmenite, rutile etc. as it occurs in the beach sands of Australia, USA, South Africa, West Africa and India.

Zircon invariably contains hafnium. There are fourteen zirconium minerals of some importance and all of them contain hafnium. It has been observed that the hafnium content in the minerals originating from syenite rock is less than in those occuring in granite.
