Title: High Resolution vs. Standard Resolution: How an increase in resolution using a field portable spectrometer affects quality of data
Author: Lori Shelton Pieniazek
Standard resolution of a field portable spectrometer at 3nm (UV), 8nm (VIS) and 6nm(NIR) has been used successfully in the geological remote sensing and mining industry for a variety of applications.
Alteration mapping has been key for finding different mineral assemblages that indicate an area of interest. Using a higher resolution field spectrometer has proven to be beneficial in understanding and identifying new features in a variety of different mineral groups and subgroups.
A study was conducted using three different field spectrometers, each with different resolutions.
As you increase resolution, features that are not visible with a standard resolution spectrometer appear in all three ranges (UV,VIS,NIR) thus yielding a better understanding of alteration changes and geochemical conditions.
We present findings from a range of sites across the southwest region, from the Isles of Scilly in the west to Torbay in the east.
These areas of interest showcase key features of fault zones such as displacements, damage zones and their geometries as we attempt to identify key reservoir characteristics and piece together post-Permian reactivation events that have affected the region.
