A new type of sedimentary structures, syn-sedimentary compression structures, is found and distinguished from these structures.

Sand control and oil control effect of syndepositional structure in Jiyang depression;

Based on analyzing syndepositional structure of Tiefa basin,the vertical and transversal syndepositional tectonic-units were set out and the coal-controlling characteristic and coal-accumulating condition of syndepositional tectonic-units were analyzed and the control action of synbasinal structure acting on coal-rich zone and coal-accumulating contre was summed.

The control of the Tertiary syndepositional structures on the deposition,the accumulation of oil and gas in the Dongying Sag,the Bohai Bay Basin has been discussed systematically through the analysis of the relationship between structure,deposition and reservoir forming.

In this article,the combinative method of qualitative and quantitative analyses is adopted to study the synsedimentary structure framework and its controls on the thickness of extra thick coal bed & oil shale.

K-shpae structure is a set of synsedimentary structures which grow in uni-lateral fault basin.

The ideas and concepts regarding to the analysis of syntectonic sedimentation are briefly introduced together with the investigation approaches and its potential implications to the research of regional tectonic deformation processes.

Equal-spaced thickness method for quantitative evaluation on the activity of syndepositional nosing structure-taking Dawangzhuang nosing structure as example.;
