| Article Name : | | | Morphotectonic Studies Of Area Around Lanja, District Ratnagiri: Remote Sensing Technique | | Author Name : | | | Dikshit V.

By applying various methods of remote sensing enhancement techniques, geomorphological, lineament and lithological maps can be prepared. For this purpose, LANDSAT ETM+ images are used as a base data. The lineament analysis indicates that the most dominating lineaments are N-S and NW-SE while others are ENE-WSW. The geomorphic analysis of the study area indicate that presence of two distinct geomorphic areas; 1) western plateau region and 2) east-west trending ridge and valley landforms east of curvilinear lineaments. Lithologicallythe area is covered by basaltic lava flows of Deccan Traps and its western part is covered by lateritic caps of varying sizes and shapes. The outcrops of older Kaladgi sedimentary quartzite occur as small inliers in the centre of the study area.The spatial distribution and arrangement of geomorphic features and their correlation with lineaments and lithology is successfully applied to decipher the morphotectonic studies of the area. | | Keywords : | | |
