Whitehead, N.E. 1994 Possibilities of thermoluminescence dating and electron spin resonance dating within the Institute of Geological and Nuclear Sciences . Lower Hutt: Institute of Geological & Nuclear Sciences Institute of Geological & Nuclear Sciences science report 94/36 8 p.


Abstract: The Nuclear Sciences Review suggested that we establish thermoluminescence dating in this Institute. The technique is reviewed and it is suggested that electron spin resonance (ESR), a parallel technique would be more appropriate. The Institute of Geological and Nuclear Sciences Limited already has experience in the technique and has published in the field. Equipment is available on campus. The main use could be for dating quartz, perhaps as old as 1 Ma. However the technique is labour intensive and expensive; it is also subject to more uncertainties than existing techniques in use here. It is recommended that it be used, but as a technique often requiring support and confirmation from other techniques. Usually it will be useful in the age range 0-350 ka, about the same as U/Th series dating. Commercial application of thermoluminescence (and hence probably ESR as well) would not be profitable because of the subsidised analysis offered in the Wollongong University Laboratory. (auth)
