摘要：

The Eocene flysch of Middle Dalmatia comprises several beds that are interpreted to have been deposited from reflected sediment gravity flows. Their compositions are similar and two bed types are differentiated: complex beds that are debrite‐plus‐turbidite couplets, and turbidites. The sequence alternations in the turbidite part of the bed, opposing ripples within the same bed, and opposite flow directions indicated by flutes and ripples are indicative of flow reflections. The influence of seiches is suggested by the occurrence of symmetrical (oscillation) ripples. The palaeotransport directions of reflected flows show wide dispersal. A geometry of small, fault‐controlled sub‐basins with centripetal palaeotransport patterns is proposed. Copyright © 1990, Wiley Blackwell. All rights reserved
