Within the Jones Mountains, which form part of the Thurston Island crustal block, up to 700 m of Miocene ( c. 10 Ma) pillow basalt and palagonitized volcaniclastic rocks unconformably overlie Jurassic granitic basement and Cretaceous volcanic rocks and dykes. New geochemical analyses demonstrate the...
