Spectral Geology & Hyperspectral Scanners
MMSL has over 20 years experience of working with Spectral Geology using field and laboratory visible/infra red spectrometers and airborne hyperspectral scanners for geological mapping and mineral exploration. Services include geological field work, Hyperspectral Survey planning & supervision, follow-up spectral surveys using field/lab spectrometers and staff training and mentoring in Spectral Geology and Hyperspectral Image Processing & Interpretation.
The example here shows HyMap data over a folded meta-sedimentary limestone shale sequence. The carbonates are mapped with calcite signatures. A complex and intense alteration zone at a fold nose contains alunite, dickite, kaolinite and pyrophyllite. We also see a zoned variation in mica compositions with a central paragonite zone, intermediate muscovite zone and distal phengite zone. This anomalous alteration zone suggests a buried intrusion at the fold apex with probable mineralisation of skarn type at the margins of the central carbonate unit at the fold axis.
