Accelerator Mass Spectrometry (AMS) measurements of cosmogenic isotopes were made from erratic and bedrock samples collected in the Ellsworth Mountains, 2005-2006. Pressed AMS targets were analysed at SUERC (Scottish Universities Environmental Research Centre) to yield exposure ages.

Laboratory AMS (Anisotropy of Magnetic Susceptibility) measurements made on a collection of sill samples collected from the Theron Mountains, Antarctica, during the 2004-2005 field season. AMS involves the collection of some 1 metric tonne of oriented samples and the lab-based determination of the magmatic flow fabric of the rock. Models concerning the location of mantle plumes and triple junctions associated with the Mesozoic break-up of Gondwana in the Antarctic-southern Africa sector are not capable of independent testing, other than by geochemical and age dating methods. We determined the regional flow directions of the magmas in dyke and sill complexes in the areas of postulated plume heads and related triple points on the opposing conjugate margins. AMS was utilised to determine magmatic flow directions and constrain these with macroscopic observations of flow indicators.

Powders, solutions and residues related to erratic and bedrock samples collected in the Ellsworth Mountains during the 2005-2006 field season. For each of the rock samples analysed in the lab, a (variable) number of laboratory stages are created, including sawing and crushing residues, pure quartz separates, chemical solutions, and AMS (Accelerator Mass Spectrometry) targets.
