Short summary

This paper presents geochemical data from a suite of glacially eroded igneous rock clasts sampled from Antarctica to estimate both crustal heat production and heat flow for the continental interior. The results indicate that the interior of East Antarctica is underlain by Proterozoic continental lithosphere of average surface heat flow, providing first-order constraints on both geodynamic history and ice-sheet stability.
