Proximal and remote hyperspectral sensing for Li-pegmatite exploration

Course leader: Carsten Laukamp (CSIRO)

This one-day short course introduces hyperspectral proximal and remote sensing for Li-pegmatite exploration. Fundamentals of mineral spectroscopy theory in the context of LCT-pegmatites and opportunities for integration with complementary geochemical and geophysical data sets will be discussed, followed by hands-on exercises that allow participants to evaluate hyperspectral drill core and satellite imagery for mineral exploration.

During the morning session, hyperspectral drill core data made publicly available by the AuScope National Virtual Core Library (https://www.auscope.org.au/nvcl), will be investigated for mapping Li-ore, gangue and alteration minerals in drill cores from a range of LCT-pegmatites from across Australia. Hyperspectral and complementary whole rock geochemical data will be analysed in CSIRO’s The Spectral Geologist software (TSG^TM).

During the afternoon session, recently publicly released satellite hyperspectral-derived mineral maps from the Pilbara Craton (https://doi.org/10.25919/r8bn-f506) and complementary geophysical data (e.g. radiometrics) will be evaluated for mapping visible-near and shortwave infrared active mineral assemblages of granitoids and greenstone belts, as well as pegmatites and quartz veins.

Attendees will receive a copy of all ppt presentations and case study data.

Prerequisites:

Attendees to bring their own laptops for hands-on exercises in The Spectral Geologist software (TSG^TM; https://research.csiro.au/thespectralgeologist/; full workshop licenses will be provided to attendees) and QGIS (freely available GIS; https://qgis.org/download/).
