Basanite Hand Sample
basnhs_001. A nepheline-bearing basanite sample from Stobart, Tasmania, now in the Charles Darwin collection at the Sedgwick Museum. The olivine phenocrysts have been largely replaced by iron oxides and hydroxides by hydrothermal alteration making them appear rusty. Image from the UK Virtual Microscope.
