Abstract:
The lithotectonic setting of the northwestern part of Eastern Ghats Mobile Belt around Lathore, Lakhna and Turekela in Balangir and Kalahandi districts of Orissa has been interpreted on the basis of IRS-1C LISS-III digital data in conjunction with detailed structural mapping. The FCC (RGB = 532) is highly informative about the lithology in the above metamorphosed and deformed terrain and is conformable with the lithological map prepared through field mapping. The linearly stretched ratio image between B2 and B5 bands has clearly brought out the large scale structures, The result has confirmed the earlier study, that the area is part of fold-thrust belt in the Eastern Ghats and the individual lithotectonic groups namely Lathore Group and Turekela Group represent thrust sheets that have been successively thrust over craton.
