dc.description.abstractTidalites are preserved within a metavolcano-sedimentary succession of the Late Archaean Bababudan Group (Dharwar Supergroup) along the western boundary of the NNW-SSE trending Chitradurga greenstone belt, West Dharwar Craton, southern India. These may represent the oldest record of tidal processes in peninsular India. Millimetre thick sand-mud alternations, bidirectional cross-strata, mudstone-draped sandy foresets, reactivation surfaces indicating time-velocity asymmetry, sigmoidal cross-strata and mudstone draped flaser/lenticular bedding are displayed by the sandstone mudstone heterolithic facies in the upper part of the Bababudan succession, together implying a tidal depositional system. Thick-thin pairs of rhythmic foreset bundles correspond to neap-spring tidal cycles within a semidiurnal tidal system. Development of the studied coastal sediments suggests formation of stable platform along the western margin of the late Archaean Chitradurga greenstone belt. © 2014 Elsevier B.V.-
