lnternal-tide and internal-wave deposits are a new and important type of deep-water traction-current deposits. Based on an analysis of documented internal-tide and internal-wave deposits, five facies types can be recognized: (i) bidirectionaI cross-Iaminaled sandstone fa-cies, (ii) unidirectional cross-bedded and cross-Iaminated sandstone facies, (iii) rhythmic a1-ternating sandstone facies and mudstone, (iv) flaser, wavy and lenticular bedded foraminiferaI limestone facies, (v) sandy oolitic Iimestone facies with flaser, wavy and lenticular bedding and epsilon cross bedding, which formed in submarine channel. unchannelized continentaI slope and plateau environments respectively. Accoding to the available data and knowledge, three sedimentation models are built: some discriminating Characteristics of internal-tide and ln-ternal-wave deposits. and the distinction between them and contourites and turbidites are summed up.
