Microanalysis Sample Collection

Using microanalysis methods, rock samples are analysed for their mineralogy, mineral associations and micro-texture. To target the minerals, rock samples are cut and either mounted to glass and polished to 30um thick, or mounted in an epoxy round and the surface polished. These samples can then be observed through a petrographic microscope and analysed with scanning electron microscopes, laser ablation ICP-MS and other microanalysis techniques. These samples represent not only the cost of obtaining the sample (e.g. cost of drilling or fieldwork) but an additional cost of the expertise to prepare these samples for analysis. 

As of January 2025, we have catalogued 2658 thin sections and 17710 polished rounds, representing an extensive collection of well-characterised rock samples. This is only the beginning, and as the collection increases, these samples will be made available for further and future research, adding value to this excellent microanalysis resource.
