摘要:Remote sensing and field studies of Ambasamudram â Tenkasi transect a part of Achankovil-Tambraparni Shear Zone of south India reveal five different pattern of lineaments i.e. (i) ENE - WSW to E - W (ii) NNW - SSE to NW - SE (iii) NNE - SSW to NE - SW (iv) NW - SE to WNW - ESE and (v) N - S. Based on shear sense and field association nine prominent shear-lineaments related to D1, D2, D3 and D4 deformation have been delineated. Mean frequency, mean density and nearest neighbor analysis of shear- lineaments form a tool to distinguish the intensity of deformation and to predict the order of decreasing intensity of deformation i.e. D3, D2, D4 and D1. The random and regular patterns of individual shear-lineaments were observed and their restriction to a specific lithology and geomorphic expression are pointing towards a genetic link between them.
