Identifying and Distinguishing Copper Sulfates


Rapidly oxidizing copper deposits and secondary copper sulfate minerals associated with acid drainage can pose a considerable risk to our environment. Identifying and distinguishing between copper sulfates is vital to environmental health to avoid public concerns like contamination of drinking water aquifers, farmland, and habitats for fish and wildlife. Copper sulfates - including antlerite, brochantite, chalcanthite, cyanotrichite, kroehnite, spangolite - each have distinct spectral absorption features that allow geologists to identify them quickly and easily.

Spectral Evolution's EZ-ID software matches the target scan from your sample against three libraries of more than 1100 known minerals to provide an accurate match. EZ-ID can also perform unmixing using match regions and score tables to concentrate on the essential absorption features.

The benefits of using an oreXpressoreXplorer, or oreXpert  with EZ-ID include:
      • Quickly collect many scans
      • Cover more ground in less time for better mapping
      • Collect more accurate data for a complete picture of the area you are exploring
      • Get results immediately instead of waiting for lab analysis
      • Drill fewer holes with better results
      • Correctly identify promising samples, save on assay costs, and save your valuable logging data in the core shack

About the ore-X series:

These spectrometers deliver full-range UV/VIS/NIR capabilities from 350-2500nm. They are lightweight (7 – 11 lbs), rugged, include integral auto-exposure and auto-dark shutter, and come bundled with a rugged handheld tablet equipped with a digital camera, GPS, and voice notes that you can tag to your spectra. In addition, our DARWin Data Acquisition software saves your scans as ASCII files for use (without pre-processing) with third-party software, including chemometric analysis software.
