Automation of Micro-XRF Data Colleciton and Phase Identification

M4 TORNADO AMICS is an innovative new approach to automated mineralogy using X-ray excitation to collect energy spectra for mineral matching. This package matches the ultra-fast high resolution elemental distribution analysis of the M4 TORNADO and the automation and phase classification technology of the AMICS software. 

  • M4 TORNADO AMICS has a large sample chamber that operates at low atmospheric pressure requiring only a flat surface with no special coating or polishing. Perfect for slabbed core, hand sample slabs, and thin section billets, or even unpolished grain mounts. 
  • Quickly automate repeated measurements with a wide range of sample holders and customized measurement areas. 
  • Analyze entire samples to identify mineralogy or phases, characterize textures and associations, apply statistical calculations and report results as maps, charts, and graphs. 
  • The innovative Spectrum Tree empowers users to classify unknown phases including complex solid solutions, boundary and mixed phases.


How Can Micro-XRF Fit into My Mineralogical and Textural Characterization Workflow?

Integrate M4 TORNADO AMICS into any workflow to add geochemical and mineral maps from any prepared or un-prepared samples - drill core, hand samples, billets, thin sections and grain mounts. This innovative and robust instrument captures mineral information within a textural and elemental framework.  

  • Excellent trace-element detection limits and quick measurement times produce < 20 µm resolution phase maps that empower rapid decision making and down-selection of samples for further analysis by AMICS SEM or other techniques that require smaller prepared samples. 
  • M4 TORNADO AMICS is ideal for measurements of samples with large mineral grains such as coarse crystalline igneous rocks or heavy mineral sands, enabling quick analysis before crushing and sizing eliminates the orginial textural context  
  • The robust M4 TORNADO instrument can be forward deployed to field locations worldwide; it is easy to use, self-contained and has no consumables. When equipped with M4 TORNADO AMICS and combined with a compact SEM and field-appropriate sample preparation tools it can provide a complete on-site lithological and textural analytical solution for fast tactical decision making. 


What is Your Analytical Challenge?

Mineral Exploration

Drill Core Lithotype, Mineral and Texture Analysis

M4 TORNADO AMICS becomes a critical tool in the core characterization workflow by capturing and preserving the mineral and textural information lost when core is crushed and pulped. This original mineral and textural information, and additional geochemistry derived from it, can be used to characterize ore body geometries and develop vectors to ore in exploration environments. Spatially resolved mineral data allow contextualizing of traditional bulk geochemical and XRD analyses, and when combined with elemental mapping, M4 TORANDO AMICS provides critical information for development of robust exploration models.
Industral minerals

Heavy mineral sands analysis

Heavy mineral sands are an important source for zirconium, titanium, tungsten and rare-earth elements. M4 TORNADO AMICS is a unique solution for rapid assessment of modal mineralogy for exploration targets and production. Samples can be analyzed with minimum sample preparation with minerals sorted by size class and mineral. The M4 TORNADO is easy to use and can be installed close to production facilities, resulting in rapid data production for extremely quick tactical decision making.
Petrology and geochemistry

Spatially resolved mineralogy and trace element geochemistry

M4 TORNADO AMICS enables quantitative modal mineral and textural characterization of most geologic samples with micro-XRF. The ability to map large areas quickly allows complete sample analysis with limited bias, providing full confidence in results. Use elemental data and mineral maps as tools for more informed sample selection for SEM-EDS analysis. Target low-abundance minerals in large samples to reduce time and cost in further sample characterization and analysis by EMP and LA-ICP-MS.
