| Abstract: | Deep-water tractive current deposits found include (1) contour current deposits and (2) internal-tide and internal-wave deposits. This paper summarizes the past, present states and latest developments of the study on deep-water tractive current deposits , and points out the existing problems and prospects. The study on contour current deposits started earlier and has obtained a series of achievements which mainly include : (1) the es- tablishment of recognition criteria of contour current deposits , (2) the discovery and study of contourite drifts , and (3) the study of ancient contour current deposits. The study of internal-tide and internal-wave deposits started just recently. Now we have discovered and studied systematically some internal-tide and internal-wave deposits and recognized four types of fancies , and have also established three types of sedimentary models. The main problems existing in the study of deep-water tractive current deposits are (1) unequilibri- um of the study of contour current deposits , (2) lack of detailed and systematic study on internal-tide and internal-wave deposits , (3) the reliability of recognition criteria of deep- water tractive current deposits, (4) the origin of large-scale sediment wave in deep-water , and (5) the study of diageneses and petroliferous of deep-water tractive current deposits. The significant progress will be obtained in the study of deep-water tractive current de- posits with the solution of these problems. |
