Structures and their Succession in Peritidal Storm Microsequences: Rewa Formation, Bhainsrorgarh, Rajasthan, India

Many of the storm microsequences start with a shale-pebble-conglomerate that grades upwards into sands with parallel lamination followed successively by hummocky cross-stratification, another set of parallel lamination and wave ripple crosslamination. Swarms of flute-and groove-casts are often present at the sole of the stormlaid units. The sequence of structures indicates gradual waning of tbe flows. The outcome of the analysis reveals that the order of vertical arrangement of structural elements in storm-laid microsequences is closely similar to those on the shelves. Nevertheless, the association of emergence features or features indicating late stage emergence run-off are distinctive for deposition in shallow water bodies like lakes and lagoons.
