The study provides a first synthesis of the results which were achieved in two branches of sedimentological research, in geosciences -vs- chemical engineering, as well as by experimental studies -vs- observation, interpretation and models. The documents define the conditions which are necessary for origin and preservation of true stromatactum pattern structures (consequently also stromatactis and related fabrics). Assessment of implications for basin and environmental analysis is given. The main control factors are defined. For carbonate materials, separation of complex slurries from turbulent particle-laden gravitational flows and their separate deposition have been emphasized.
