This study provides the first attempt to combine terrestrial (in situ) cosmogenic nuclide (10Be) surface exposure dating with Schmidt hammer relative-age dating for the age estimation of Holocene moraines at Strauchon Glacier, Southern Alps, New Zealand.

We do not do radiocarbon dating of organic materials such as bone, plants, artifacts, or art work.
In the future we hope to prepare targets for protein-specific Cosmogenic nuclides are used to determine exposure ages and erosion rates of landforms and sediments, and exhumation rates of catchment basins.
Any magnetically charged particles are attracted to this and taken down a separate track, into a separate container.
The non-magnetic particles (such as quartz), aren’t attracted, and take a separate route (see video below).
Each year we train visiting students and research scientists in the sample preparation and interpretation of cosmogenic nuclide data.
The benefits include development of isotope geochemistry laboratory skills, appreciation of experimental uncertainty, and the participation in preparing one's own samples.
Cosmic rays, originating from outer space, bring rare cosmogenic nuclide isotopes (I am using Aluminium) to the Earth’s surface, where they build up in exposed rock surfaces at known rates.
The total concentration of these isotopes in a rock surface therefore represents the length of time that the surface has been exposed to the atmosphere.
So, I’ve now left my samples there with the lab staff for a series of etches with hydrofluoric and nitric acid.
I’m heading back in about a month to finish the samples off and then run them on the mass spectrometer.
For safety and QA/QC resons it is not possible to allow untrained visitors to prepare their own targets in the first couple of batches.
