With a wealth of knowledge in exploration and mineral science, PSS offer a unique perspective for geochemical and mineralogical analysis. Our highly-experienced team of specialists are equipped to provide you with the most cost-effective solution for your mineral systems, including geochemistry or mineralogy.
Portable Spectral Services provide a range of geological interpretation services including:
Portable Spectral Services offers a range of interpretations services for processing spectral and chemical data as well as consulting services for advanced studies. These services include:
Portable Spectral Services can help provide reliable QAQC to your project by developing and implementing protocols that ensures the collection of valuable data in an efficient and cost-effective manner. These initiatives will improve the reliability and quality of the results and can be applied to ongoing and future projects. Additionally, Portable Spectral Services can monitor and validate your data remotely, providing prompt feedback on the acquired data.
Portable Spectral Services can work with you to develop an appropriate workflow plan for your project that is simple and easy to follow. These initiatives can help improve the efficiency of the data acquisition process and improve the quality of the results.
Workflows include; instrument settings and measurement times, when and what quality control samples to analyse, data acquisition procedures, data validation and quality control measures.
Our staff are available to visit your site, train your team, help implement the workflows and provide ongoing remote support to personnel.
Near infrared (NIR) spectroscopy is a widely used exploration method as a simple and rapid means of identifying alteration halos and zoning at the regional and prospect scale for a number of mineralisation styles.
Many minerals are stable over limited temperature and pH ranges, and their distribution and variable spectral features (e.g. composition, crystallinity) allow for reconstruction of the thermal, geochemical environment to develop exploration models to vector towards mineralisation. E.g. Using the TerraSpec 4 ASD the the Al-OH absorption feature can be tracked and has been found to shift to higher wavelengths towards Au mineralisation at the Tropicana gold deposit (Modified from Doyle, 2007).
Orientation studies are a crucial part of maximising value from your instrument. We carry out an orientation study to determine which instrument, mode and settings best suit your needs. Alternatively, if you already have an instrument, we can help to optimise its use for your project.
For pXRF studies we can determine how various elements are likely to perform based on the composition of the material, determine which elements are ‘fit for purpose’ and identify any potential elemental interferences you may come across. While, for NIR-SWIR studies we can evaluate samples, determine if they are ‘fit for purpose’ and provide guidance on the best procedure to maximise the data. Portable XRF Services can also develop workflow procedures specific to your project and the instruments you intend to use.
For geological applications, if you have yet to determine pathfinder elements and indicators of alteration, we can review your existing data and provide information on a suitable procedure to maximise your data output in the future.
