The AA. focus on geomorphology and geomorphic variability in the Mylliem granite, one of many igneous bodies within the basement complex of the Meghalaya Plateau. Relict flat watershed ridges and topographic basins characterize the northern and eastern part of the pluton, whereas to the southwest the relief becomes higher, with steeper hillslopes and deeply incised valleys. Deep weathering and thick saprolites are abundant, as are residual landforms resulting from stripping of the saprolite : domes, tors and boulders. The major reason behind the diversity of granite landscape of the Mylliem pluton is the progress of headward erosion, initiated at the Dauki fault in the south of the Meghalaya. Headward erosion enhances local relief and hence, weathering systems. Multi-concave morphology is gradually transformed into multi-convex one, which is hypothesized to be the specific mode of plateau evolution and scarp retreat in granite bedrock
