Summary

The Scanning Electron Microscope-Mineral Liberation Analyzer (SEM-MLA) produces false-colour, mineral distribution thin-section maps. Along with the thin-section maps, the spectra provide the user with an estimate on mineral mode abundances at the thin section scale. This report presents SEM-MLA results from six thin-bedrock sections collected from the Hopedale Block in northern Labrador. The rock samples were selected for their geochemistry and lithology.
