Mg-rich ferric illite in marine transgressive and highstand systems tracts: Examples from the Paleoproterozoic Semri Group, central India

“…[Bourgeois, 1980], [Brenchley and Newall, 1982], [Hunter and Clifton, 1982] and [Hill et al, 2003] and many others). More frequent amalgamation of sandstone beds in the facies B points to shoaling.…”

Fine-grained sedimentation on the Chenier Plain Coast and inner continental shelf, northern Gulf of Mexico

“…Typical storm deposits thus consist of a coarse sand/shell layer that often contains a sharp base (representing an erosion surface) grading upward into finer overlying mud. Deposits of this description have been observed and identified as storm-derived units in many shallow marine environments (e.g., Hayes, 1967;Reineck and Singh, 1972;Morton and Winker, 1979;Bourgeois, 1980;Morton, 1981Morton, , 1988Figueiredo et al, 1982;Dott, 1983;Bentley and Nittrouer, 1999). The occurrence of shell and sand horizons overlain by finer units in cores such as OBC and OMLb forms a vertical sequence similar to facies interpreted as storm beds on the eastern Texas inner shelf (Morton and Winker, 1979;Morton, 1988).…”

“…Fine-grained sediment deposited in shallow marine environments generally contains physical stratification when first deposited (e.g., Nittrouer et al, 1985). The degree to which original sedimentary architecture is preserved depends upon the relative rates of accumulation and biogenic or physical mixing at a given site (e.g., Bourgeois, 1980;Nittrouer and Sternberg, 1981;Dott, 1983;Nittrouer et al, 1984Nittrouer et al, , 1985Bentley and Nittrouer, 1999;Wheatcroft, 1990). Preservation of original bedding is favored by rapid accumulation, which buries stratigraphy below the mixed layer where bioturbation or physical mixing diffuses the contrast between sedimentary layers (e.g., Berger and Heath, 1968;Boudreau, 1994).…”

Sedimentary record of mid-Miocene seismotectonic activity in the Sinop Peninsula, north-central Turkey

“…The characteristics of the lower sandstone unit, ~2.5 m thick, differ from those of the hanging-wall sandstone and suggest deposition in an upper shoreface environment (Clifton, 1976(Clifton, , 1981Bourgeois, 1980;Walker and Plint, 1992;Ainsworth and Crowley, 1994). Wave near-bottom orbital velocities were ≥0.7 m s -1 , often >0.9 m s -1 (Allen, 1982, fig.…”
