Remote sensing methods are being developed for detecting and mapping carbonatite complexes. Analyses of Airborne Visible/Infrared Imaging Spectrometer (AVIRIS) and Thermal-infrared Multispectral Scanner (TIMS) data of the Mountain Pass, California and Iron Hill, Colorado complexes show that specific Al-OH, CO3, Fe2+, Fe3+, and Nd3+ minerals can be identified and mapped using the AVIRIS data, and the main alkalic lithologies can be mapped using TIMS data. The Advanced Spaceborne Thermal (ASTER), which has 14 bands and is planned for launch by NASA during 1998, should provide the capability to map carbonatite complexes that are reasonably well exposed.
