Press Release Summary:

EZ-ID Mineral Identification Software helps geologists to understand the crystallinity changes, alteration pattern shifts and geochemical conditions. EZ-ID supports spectral scalars for Al-OH bonds, ISM, CSM, Mg-OH bonds, Fe-OH bonds and Al-Fe-Mg bonds. Software enables geologists to identify alteration zones and mineral changes associated with them.

EZ-ID Adds Scalars to Better Characterize Alteration

SPECTRAL EVOLUTION’s EZ-ID mineral identification software is now available with spectral scalars that can enhance the geologist’s understanding of crystallinity changes, alteration pattern shifts and geochemical conditions.

EZ-ID now supports spectral scalars for Al-OH bonds, kaolinite crystallinity (Kx) illite spectral maturity (ISM), chlorite spectral maturity (CSM), Mg-OH bonds, Fe-OH bonds, Fe3t (mineral type), Fe3i (mineral intensity) and Al-Fe-Mg bonds.

Al-OH

The Al-OH absorption feature at 2200nm wavelength position provides indication of geochemical conditions at the time of alteration. 2160—2240 wavelength variations.

Kx

Kaolinite crystallinity influences the shape of the Al-OH feature. A Kx greater than 1 indicates kaolinite produced by weathering; less than 1 is associated with kaolinite produced by high temperature alteration events. The lower the Kx, the higher the formation temperature.

ISM

Values greater than 1 indicate a low grade metamorphic illite; less than 1— illites produced at higher temperatures.

CSM

Values greater than 1 indicate a low metamorphic grade chlorite; less than 1 are chlorites produced at a higher temperature alteration event.

Mg-OH

The wavelength position of this feature near 2350nm indicates geochemical conditions at the time of alteration.

Fe-OH

The wavelength near 2260nm position of this feature indicates geochemical conditions at the time of alteration.

Fe3t

Hydroxide-type Fe+3 minerals typically have Fe3t values greater than 900nm; oxide type Fe+3 minerals have vales less than 900nm.

Fe3i

The higher the Fe3i value the more intense the FE+3 absorption.

Al-Fe-Mg

Reports the wavelength of the deepest absorption feature of these three. Features centered in 2160-2370nm range.

The scalars provide an extra toolset for geologists identifying alteration zones and the mineral changes associated with them.

In addition to using scalars and EZ-ID’s three mineral libraries for mineral identification, with our Custom Library Builder software module, EZ-ID also allows you to scan known samples and quickly build a custom library for a particular project, mineral, location, and more. You can select pre-defined metadata fields or define your own.
