Abstract:
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.

| Quality: | The quality of the samples is excellent as the majority of the lithologies we sampled were quartz-rich sandstones and quartzites. Initial laboratory results confirmed that these samples contain abundant material for analysis. | |
