EZ-ID Mineral Identification Software for Spectral Evolution Field Portable Spectrometers

Built into our DARWin SP user interface, EZ-ID provides real time mineral identification for field or lab use. Scan your target data and immediately match it against a known library, such as the USGS library which is included with EZ-ID. Or choose the optional SpecMIN library or the new GeoSPEC High Resolution Library comprised of scans of samples from the Colorado School of Mines Museum collection, or create your own custom built library. EZ-ID provides a Library Builder software module so you can quickly and easily create and add to a custom library.

EZ-ID makes target mineral identification easier and more accurate with oreXpress, oreXplorer and oreXpert field spectrometers by providing access to three libraries:

  • USGS library which includes the JPL library – 470 spectra for 314 minerals
  • Optional SpecMIN library – 1528 spectra for 494 minerals
  • Optional GeoSPEC High Resolution Library – 688 spectra for 239 minerals

By ordering all three you have access to 2600 spectra for 1047 minerals.

EZ-ID includes scalars to better understand geochemical conditions at alteration.

EZ-ID Mineral Identification Software

Our EZ-ID software allows you to quickly identify minerals of interest, match them against existing libraries (like SpecMIN, USGS or GeoSPEC), or create your own custom library. EZ-ID software provides:

  • Fast and accurate identification of unknown minerals to known library samples
  • Easy-to-use—just collect your scan using the oreXpress, oreXplorer or ultra-high resolution oreXpert and see results in real time.
  • Scalars provide a geologist with a better understanding of mineral formation conditions.
  • Software provides a weighted score for best matches.
  • Save spectral match regions of interest for comparisons when looking for similar minerals.
  • The Library Builder allows you to create your own custom library of minerals.
  • Optional conversion of ASD files for use with EZ-ID—save your existing libraries and databases.
  • EZ-ID works through the DARWin SP Data Acquisition software interface for all Spectral Evolution
    spectrometers and spectroradiometers.

With EZ-ID, the mineral identification capabilities are built into the spectrometer, so you have instant access in the field. The results include more accurate identification, faster identification and the ability to take more sample scans in less time.

Compatibility with 3rd Party Analysis Software

Because DARWin saves scan data in an ASCII format it is ready-to-use with a number of popular 3rd party analysis software, including SpecMIN, GRAMS, and The Spectral Geologist (TSG).

SpecMIN

SpecMIN is a mineral identification system that includes an extensive library of reference spectra for minerals, wavelength search/match tables, physical properties of each species in the database, and literature references for the infrared active mineral phases. SpecMIN is available with SPECTRAL EVOLUTION’S EZ-ID.

For mineral identification, SpecMIN offers over 490 infrared active mineral species with almost 1528 spectra. The automated spectral match tables present matches by:

  • Major and minor absorption features
  • Mineral species
  • Mineral groups

Feature analysis tables are available for individual species and diagnostic absorption features for each mineral selected. There is also an automated search/match feature for identification help. SpecMIN is a product of Spectral International, Inc.

GRAMS

GRAMS is a suite of software programs for visualizing, processing, and managing the spectroscopic data you collect. It offers tool to capture, store, process, and report data. It has a graphical multivariate analysis tool for building both quantitative and qualitative models for discriminant analysis. GRAMS provides:

  • Advanced processing routines, data comparison, and visualization
  • Spectral database provides a scalable data management tool
  • Spectral pattern matching/library searching
  • Chemometrics software for deploying chemometric calibration models

GRAMS software is a product of Thermo Scientific. For more information on GRAMS, click here.

GRAMS

The Spectral Geologist (TSG)

TSG is a suite of tools for geological analysis of spectral reflectance data of minerals, rocks and soils, drill cores, and chips. With TSG, a user can generate a detailed analysis of multiple spectra, use core images and ancillary data streams, and work with small or large data sets. TSG features the following capabilities:

  • Analyze any size spectral data set
  • Make thousands of spectra into calculated mineralogical indices for analysis of specific mineral characteristics, such as composition
  • Automate the mineral interpretation process
  • Integrate spectrally derived data with imported geochemical and geological mine data
  • Visualize and plot results in a wide range of formats and views

Our rugged and reliable field spectrometers can help you identify and map mineral pathfinders for vectoring to ore deposits. They deliver mineral identification in the field in real-time  so you can explore more territory and make more informed decisions on where to drill to maximize exploration outcomes.

In the core shack you can map alteration and eliminate unnecessary assays on cores that show no potential, reduce the time logging takes and build a digital archive of your results.
