(A) Geological map of the Marinkas Quellen carbonatite complex with an inset showing its location in Namibia. The geological map was modified after Smithies and Marsh²². (A.1) The zoomed-in area shows the footprint of the hyperspectral UAV-based survey. (B) Geological map of the Siilinjärvi carbonatite complex with an inset showing its location in Finland. The geological map was modified after the Geological Survey of Finland²⁶. (B.1) The zoomed in area shows the footprint of the hyperspectral UAV-based survey.
