| Abstract: | This paper aims to assess the morphological signatures of tectonic features (faults) on the basis of multi sources spatial
data analysis. For that purpose, the present authors selected the southern part of Baromura hill of Tripura, which has been
discussed very little in the scientific literatures. An extensive field work was done in the assumed faulted areas to understand
the geomorphic signatures of faulting. In the field, GPS was used for fixing the ground control points. Scanned Survey of
India (SOI) topographical sheets, SPOT PAN and Land sat band-5 was used for digital analysis. An old DEM on IRS LISS-III FCC
was also consulted for final mapping. Two clear lineaments (Faults) were detected from field observation on southern Baromura
hill. Apart from these, another one was found in the outer part of this hill range. An attempt was made to explain the morphological
signatures of those faults by density slicing on radiometric data based on emittance of different physical components. Finally
a geomorphic map with main tectonic features of Baromura was prepared for future disaster management planning. |
