Abstract
⺠The present study documents that fabric evolution during weathering and compaction at basement-cover interfaces has important implications on continental deformation. ⺠Anisotropy of magnetic susceptibility (AMS), especially AMS ellipsoid orientations and shapes are a valid marker for the progressive imprint of horizontal compaction over primary fabrics in unweathered to saprolitic weathered granitic. ⺠Laterites, characterized by the well-developed clay-/ mica-fabric S3d, acted as a structurally weak and impermeable layer during crustal fluid flow. Hence, laterite horizon is a site, which is favourable for decollement tectonics at the basement-cover interface.
