Tephrochronology & Materials Commercial Services

Micro-tephra
We are one of the few places that has a dedicated cryptotephra extraction laboratory, facilities for preparing samples for analysis (grinding and polishing), and analytical equipment for analysing tephra. Major element analyses are carried out on our JEOL-8600 electron microprobe with SAMx software. It is equipped with 4 wavelength-dispersive spectrometers and capable of analyzing, mapping and imaging a range of geological and archaeological materials. Our lab performed well in the tephra analysis inter-laboratory comparison (lab number 25) see: Kuehn, S.C., Froese, D.G., Shane, P.A.R. and INTAV Intercomparison Participants. 2011. The INTAV intercomparison of electron-beam microanalysis of glass by tephrochronology laboratories: Results and recommendations. Quaternary International, 246, 19-47. doi:10.1016/j.quaint.2011.08.022

 

Our team also has extensive knowledge of archaeological and Quaternary dating issues, and our strengths include: statistical data analysis, igneous petrology, glass chemistry, and environmental site investigation.
