Summary(Plain Language Summary, not published)
The Targeted Geoscience Initiative (TGI-4) is a collaborative federal geoscience program that provides industry with the next generation of geoscience knowledge and innovative techniques to better detect buried mineral deposits, thereby reducing some of the risks of exploration. For many geochemical studies, such-as environmental or mineral exploration studies, the very low detection limits of ICP technology are less important than time delays, which make real-time on-site decisions impossible, thus requiring expensive subsequent field trips to clarify geochemical issues. For many such situations Total X-ray Reflection Spectroscopy (TXRF) technology may be more appropriate, with the potential for analyses at low part per billion-level detection limits within a few hours of sampling. From the sampling and analytical protocol, it is demonstrated that careful attention to detail makes TXRF analysis a valid method for field-based trace element analysis at low ppb levels.
