The Tibetan Plateau holds clues to understanding the dynamics and mechanismsassociated with continental growth. Part of the region is characterized byzones of ophiolitic melange believed to represent the remnants of ancientoceanic crust and underlying upper mantle emplaced during oceanic closures.However, due to the remoteness of the region and the inhospitable terrain manyareas have not received detailed investigation. Increased spatial and spectralresolution of satellite sensors have made it possible to map in greater detailthe mineralogy and lithology than in the past. Recent work by Yoshiki Ninomiyaof the Geological Survey of Japan has pioneered the use of several spectralindices for the mapping of quartzose, carbonate, and silicate rocks usingAdvanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) thermalinfrared (TIR) data. In this study, ASTER TIR indices have been applied to aregion in western-central Tibet for the purposes of assessing theireffectiveness for differentiating ophiolites and other lithologies. The resultsagree well with existing geological maps and other published data. The studyarea was chosen due to its diverse range of rock types, including an ophioliticmelange, associated with the Bangong-Nujiang suture (BNS) that crops out on thenorthern shores of Lagkor Tso and Dong Tso ("Tso" is Tibetan for lake). Thetechniques highlighted in this paper could be applied to other geographicalregions where similar geological questions need to be resolved. The results ofthis study aim to show the utility of ASTER TIR imagery for geological mappingin semi-arid and sparsely vegetated areas on the Tibetan Plateau.
