Western Eyre Peninsula, Coulta Subdomain and Nuyts Subdomain
On western Eyre Peninsula, the Coulta Subdomain merges with the Nuyts Subdomain which is dominated by variably deformed ca. 1670-1610 Ma granitoids, mafics and felsic volcanics. Deformation is attributed to the Kalaran Orogeny which generated a major fold belt or shear zone, the Fowler Shear Zone, ca. 1600-1540 Ma.

Famous quotes containing the words western and/or eyre:
“So motionless, she seemed stone dead—just seemed:
She was too old for death, too old for life,
For as if jealous of all living forms
She had lain there before bivalves began
To catacomb their shells on western mountains.”
—Edwin John Pratt (1882–1964)
“Balance is the enemy of art.”
—Richard Eyre (b. 1943)
