1:50,000 geological mapping was conducted at the head of the Ferrar Glacier including the massifs of Pivot Peak, Terra Cotta, Knobhead, Table Mountain and Rotunda. The exposed rocks are almost entirely Beacon Supergroup intruded by Ferrar Dolerite. Trace fossils and lithological associations were used to interpret depositional environments, about which there has been some debate.
Rock samples collected from this study are held at GNS Science. They are not loaded into the PETLAB database, but should have catalogue numbers. Please contact John Simes (J.Simes@gns.cri.nz) or Nick Mortimer (N.Mortimer@gns.cri.nz) for more information.
