Quantitative estimation of rare earth element abundances in compositionally distinct carbonatites: Implications for proximal remote-sensing prospection of critical elements

Veronika Kopačková-Strnadová, Vladislav Rapprich, Virginia McLemore, Ondřej Pour, Tomáš Magna
2021 International Journal of Applied Earth Observation and Geoinformation  
A B S T R A C T Rare earth elements (REE) became a strategic raw material in the 21 st century and carbonatite-related deposits frequently carry potentially economic levels of these critical metals.  ...  In contrast, modern Remote Sensing (RS) -e.g. proximal remote sensing or imaging spectroscopyhas become a novel tool for detecting and quantifying geological materials as they offer an efficient, non-destructive  ...  We are grateful to Dewashish Upadhyay for assistance during field campaigns in India and Radko Š arič for help with identification of the East African Rift samples in the collections of the Czech Geological  ...
