Abstract
Image processing software is used in many ways but as far as I have seen, it has not been used to analyze SEM or petrographic thin sections. This use will be very beneficial at the very least as a compliment to current mineral and lithologic studies but the potential is limitless with the right programming.
The goal of my thesis was to test for the potential of using standard image processing software, IDL and ENVI, to analyze these thin sections. I have found it to be very feasible to use software packages already available for topographic and satellite image analysis. Isolating pixels and adjusting the display colors have proven to be a relatively simple tasks that can be put to use by someone with very little experience using this software. Though, more work will need to be done to put this to greater use, these programs have demonstrated a great deal of potential for this use in the field.
