Approximate Mineral and Chemical Composition
Pegmatite deposits typically are commonly associated with tin (Sn), and especially, tantalum (Ta) mineralisation. Nearly all of Australia’s resources are associated with granite pegmatites of Archean age, found within the Pilbara and Yilgarn cratons of Western Australia.
