"Harveys Return. The steep walking track to the cove, once a supply route for the Cape Borda lighthouse, reveals

a sequence of laminated and folded metasandstone and quartz–biotite schist. A regular quartz-rich and biotite-rich layering (zebra rock) largely reflects original sedimentary layering enhanced by metamorphic differentiation." Martin C Fairclough (Geological Survey Branch, PIRSA) Thank you.

 

Harvey's Return,

Kangaroo Island,
