Abstract

We present calculated radiogenic crustal heat production values (ca. 1500 determinations) from available geochemical data (from OZCHEM, published literature and unpublished data) from exposed outcrops from the Australian Antarctic Territory (AAT). Geothermal heat production is derived from the radiogenic decay of the radioactive elements, primarily, U, Th and K, elements that are primarily concentrated in the earth's crust. In this report, we briefly assess the magnitude and heterogeneity of crustal heat production across the major regions within AAT. This information has been compiled as a foundation for subsequent, more comprehensive, geothermal heat assessments of the AAT (including heat flow, and thermal conductivity determinations) for the purposes of ice sheet modelling studies addressing the dynamic behaviour of the east Antarctic Ice Sheet.
