Deccan Plateau uplift: insights from parts of Western Uplands, Maharashtra, India

Abstract

AbstractThe western edge of the Deccan Plateau (=Western Uplands) has been depicted in its evolutionary models to be a contiguous crustal block exposing structurally undisturbed subhorizontal stacks of Deccan Trap basalts.The geomorphological and morphometric characteristics of this terrain, Quaternary fluvial sediments capping the Deccan Traps in some river basins, compounded with deformation features in the basalts, and in the overlying sediments, are compiled here. They demonstrate that the Western Upland region of the Deccan Plateau may be constituted of no less than three blocks with differential Quaternary uplift histories, rather than the entire region experiencing a unified uplift.
