Rock Assemblage Library: MLA Pilot Study

The AuScope NVCL Rock Assemblage Library project aims to validate the interpretation of HyLogger spectra for representative mineralogies. This data collection includes the data used the 2021 Rock Assemblage Library: MLA Pilot Study (Mineral Resources Tasmania, Geological Survey Technical Report 23). The Hylogger interpretations are validated by calculating mineral proportions using the MINSQ algorithm from (a) XRD analysis to provide the mineral assemblage, (b) microprobe analysis to provide mineral compositions and (c) XRF analysis of the whole sample. Additional validation was provided by quantitative XRD and petrological thin section and MLA. \nLineage: This data was collected by Mineral Resources Tasmania.
