Pining for an anomaly: Biogeochemical mapping of the Cobar Basin for mineral exploration at regional to local scales.
… performed using inductively-coupled plasma-mass spectrometry (ICP-MS) and portable X-ray fluorescence spectrometry (pXRF). Concentrations of most elements in the needles reflect variations in underlying lithology, even in areas with alluvial cover. Concentrations of non-nutrient trace elements …

Characterization of soils via portable X-ray fluorescence spectrometer
… in nature and require sample modification. Portable x-ray fluorescence (PXRF) spectrometry is a proximal sensing technique which provides elemental data in-situ, in seconds. This study examined the potential of using PXRF for soil pH and CEC prediction, using a diverse set of soil samples. …

Using Portable X-ray Fluorescence to Predict Physical and Chemical Properties of California Soils
… in a proximal soil sensing technique known as portable X-ray fluorescence spectrometry (pXRF). pXRF analyzers use high energy Xrays that interact with a sample to cause characteristic reflorescence that can be distinguished by the analyzer for its energy and intensity to determine the chemical …
